Hi there,
I have installed and activated the Regenerate Thumbnails plugin, but I noticed that the image quality of product reviews has decreased. As a result, I no longer wish to use it.
However, after deactivating the plugin, the image URLs did not revert and remain unchanged – https://snipboard.io/OZAcfn.jpg
Could you please advise on how to resolve this issue?
Best regards,

Hi,
How to disable this plugin from automatically regenerating thumbnails, from happening when turning on/off multiple plugins at once when troubleshooting plugin interference.
Recently i’ve noticed extra thumbnails being created beacuse of an automatic thumbnails regeneration by this plugin.
How to avoid this from happening?
]]>Hey! I have a strange problem I can’t seem to find a solution. In the functions.php we change the specs of the “medium” size like this
function imagesizes_nf() {
update_option('thumbnail_size_w', 350);
update_option('thumbnail_size_h', 0);
update_option('thumbnail_crop', 0);
update_option('medium_size_w', 480);
update_option('medium_size_h', 270);
update_option('medium_crop', 1);
add_image_size('single', 1920, 600, true);
remove_image_size('2048x2048');
remove_image_size('1536x1536');
}
add_action( 'after_setup_theme', 'imagesizes_nf' );For the other sizes we are changing this works great. But there seems to be a problem with “medium”. When we start regenerating thumbnails and delete old sizes, “medium” gets deleted. If I then regenerate everything it does generate the size “medium” but immediately sees it as an old size (see screenshot).
Anybody has an idea why that could be?
]]>Hi

Jpg images are found and thumbnails settings from the theme are working correctly.
but webp images are not found, and this causes problems w regards to the settings from the theme not working for webp files.

Seems like:
– its not the theme

Thanks alot for your help!
Hi,
I have disabled all sizes by using the Perfect Images plugin, but the Regenerate thumbnails plugin still sees them. Is it possible to stop showing these sizes if they are actually not available? Thank you in advance.
]]>Does not work with the latest version WooCommerce 9.1.2, WordPress 6.6. The process sometimes hangs. Does not regenerate.
]]>Hi there,
We’re running a WP site using a Lightsail instance and when I try and regenerate thumbnails it proceeds through the list without errors, but checking using FTP and trying to access the urls, the files are not being generated. This is working on my local instance on the site so it must be to do with Lightsail. Any help or alternative methods to get these new sizes working would be amazing – thanks in advance
]]>Hi,
Does the plugin work with WP 6.5.4?
Thanks, Gerd-E.
]]>If PDF thumbnails are not generated for any reason, you can select the attachments in the Media Library and apply Regenerate Thumbnails, but it fails with Skipped Attachment ID nnnn (filename): The fullsize image file cannot be found in your uploads directory at . Without it, new thumbnail images can't be generated.
Looks like this was introduced in 3.1.2, as wp_get_original_image_path() returns NULL for non-image attachments. A patch to fix is:

I changed a plugin which removes a couple of sizes and adds a couple of new sizes. They have been shown here
- 1536×1536:?1536×1536 pixels (proportionally resized to fit inside dimensions)
- 2048×2048:?2048×2048 pixels (proportionally resized to fit inside dimensions)

- banner_1920x1200:?1920×1200 pixels (proportionally resized to fit inside dimensions)
But when I run with these options it does not seem to do anything. there used to be an old
phone_size
640 × 853
tablet_size
768 × 1024
Can they did not get deleted in the batch file mode. However if I go into an individual image I can press regenerate and it will correctly say that there are some new sizes and some old unused sizes

]]>trying to get all category images on the linked page to display in the identical height without cropping and without undesirable disproportionate skewing and assuming this plugin is intended for that. however, after installing the plugin and checking the tools section, there are only 2 buttons as options, 1 reads “regenerate thumbnails for all 534 attachments and the other that reads “regenerate thumbnails for the 286 featured images only”. don’t see the options for desired thumbnail sizes etc. FYI not sure how to insert a screenshot into this post from a jpg image found on my hard drive. i only see options for inserting images from a url.
]]>The thumbnails generated by your plugin are not displaying correctly on my website. Instead of showing the designated images, blank placeholders or broken images are appearing. How can I troubleshoot and fix this problem to ensure proper thumbnail display.
]]>Hello, this is to ask about thumbnail images general functioning rule in regards to Regenerate Thumbnail plugin, as even with severally customized settings, from the WP and theme defaults, thumbnail images generating is seems going wild or similarly uncontrolled.
On the website i’m working on, there are per Regenerate Thumbnail plugin settings, totally a 13 images sizes. Please see the actual settings screenshot https://filebin.net/b136nouasuzn127t/prob-1.png
Still, among the set thumbnails sizes there are repeated sizes for different class names, and there are actually the 5 image sizes.
On the website, at media gallery there are currently around 24,900 images, registered in use. Please see the screenshot https://filebin.net/b136nouasuzn127t/prob-2.png
During processing thumbnail regeneration, the plugin is, at 75% of completion, showing 118,252 removed and 189,355 thumbnails regenerated, please see the screenshot https://filebin.net/b136nouasuzn127t/prob-3.png
-meaning that, there would be around 252,473 upon thumbnails finalized processing. All that with above data of total registered images around 24,900 x 5 image sizes, should total 124,500 thumbnail images.
How does the plugin treats the repeated sizes as shown on the screenshot 1?
Hope to get an advice on this huge question in regards to WP websites resource sustainability,
thank you, regards
]]>Hello, could you advice how to have plugin regenerating thumbnails from the specific count of media id, as at my current workplace, there are everyday/occasional power outages that, after short interruption, force me to repeat the entire plugin processing from the (re)start?
]]>Hi I’m getting when I try to regenerate the thumbnails of an image:
ERROR: The current image editor cannot process this file type.
The file is a mime type image/jpeg
On the chrome inspector I see a Status Code: 415 Unsupported Media Type
On the database the in wp_posts table, column post_mime_type is image/x-citrix-jpeg, I’ve tried to change it to image/jpeg but the issue didn’t go away.
I’ve tried with images that were in post_mime_type already in image/jpeg but didn’t work
I have a plugin to manage “Extra File Types” and I’ve made sure image-citrix-jpeg and image/jpeg are enabled
Not sure how to further troubleshoot the issue. Thank you !
]]>Hello,
When attempting to use this plugin to re-generate our images (hosted in an S3 bucket/ CDN with mediacloud) It states:
Skipped Attachment ID?1651?(woocommerce-placeholder): The fullsize image file cannot be found in your uploads directory at?https://cdn.WEBSITE.co.uk/woocommerce-placeholder.png. Without it, new thumbnail images can’t be generated.
However, the image URL does load the full size image ? So it’s found and the CDN url is correctly shown.
Any ideas on how to fix ?
]]>I ran Regenerate Thumbnails for the first time yesterday and now the view of all images in the Media Library are stretched horizontally on the “attachment preview” (ie, when clicking to preview an image in Media Gallery).
I would rather not restore site to backup because it will delete hours of other work.
How can I undo?
]]>Hello!!!
When I try to fix my images, many of them are skipped due to Could not read image size.
But, when I look at the image in the gallery, it clearly says what size they have.
I use WP Offload Media and Amazon S3, could this have something to do with it?
]]>I regenerated my complete media after installing a new theme (Enfold by Kriesi) and now my backup increased from 700MB to 3,5GB! i Figured out that it generated up to 17 thumbnails and many of them are up to 7 times bigger than the original! What can i do?
]]>Hello!
I would like to ask for help in finding an unusual problem.
On my page translated by the WPML plugin, I found that the images arrive in the original language in the sizes I set and generated by the Regenerate Thumbnail plugin. On the other hand, when I change the language, they are retrieved and printed in the (old) sizes originally used by WordPress: https://prnt.sc/vDl-QVNxtCsS
After a long review and testing, I came to the conclusion that although the plugin indicates on the WordPress admin page that the required (new) image size has been generated – correctly: https://prnt.sc/0UOn-warw8Sc, it only “Regenerate Thumbnails” after pressing the button, they are updated on the frontend page: https://prnt.sc/Yb0CCRAQr9Sq
Isuspect that there may be a database problem, or perhaps some cache may be emptied in such a case.
Thanks in advance for your help!

]]>Good afternoon!
Thank you for this awesome plugin. I really like it, but as it seems, I changed WordPress-themes a bit too much in the last decade :s so I have used a lot of different image sizes. When first applying your plugin, I had a lot of errors on my website. However, on this help-page I read about a feature “Update the content of posts to use the new file sizes”…. but I don’t see it! I only see the Skip and Delete-options. Is this option deleted from the plugin?
]]>Generally, on a small amount of images works fine, but if there are a lot of them (thousands) it stops being useful because it doesn’t handle JS/Connection errors.
EVERY JS error in EACH run should NEVER fail to re-try (at least 1-10 times) and then skip it if it still can’t be done.
Example of an unhandled error:
build.js?ver=3.1.6:2 Uncaught TypeError: Cannot read properties of undefined (reading 'hasOwnProperty')
Relates to this part:
o = null !== n && n.hasOwnProperty("responseJSON") && null !== n.responseJSON ? n.responseJSON.hasOwnProperty("data") && null !== n.responseJSON.data && n.responseJSON.data.hasOwnProperty("attachment") && null !== n.responseJSON.data.attachment ? {I also tried ofc to hit Pause & Resume, but it doesn’t have any effect once it fails.
This is very frustrating, because it doesn’t remember even when it ended, so if I want to re-try, it has to go ALL the things it already regenerated – thousands of files – it should have a cache of what it recently already successfuly regenerated.
Also I’ve noticed that it fails to read files with diacritics (but that may be PHP+server setting).
And for some reason it seems to also go through PDFs – why? PDFs are not images…
Thank you for your work ! ?? I’m having great hopes since this should be very easy to fix – you can pass it on straight to the developers, thank you. (Please don’t ask me to “turn off” plugins etc… this is purely issue of this plugin, nothing else)
]]>Hello,
After update ot theme, the thumbnails for the featured images changed, no longer square, some became blurry.
I have installed your plugin to regenerate them.
I set up thumbnail size 350 by 350 px. and asked to regenerate the featured images thumbnails. But I got an error:
“Skipped Attachment ID?14548: SyntaxError: Unexpected end of JSON input”
For all the hundreds of images, line after line..
Can you help with that, please?
Thank you.
]]>Hi ??
Have a WooCommerce website with images of all different sizes.
The plugin works great for about 50% of the thumbnails, but it seems to also skip images.
For example, I have tried to regenerate the images on this page for a few times now: https://www.catsfavorites.com/verzorgingsproducten/voedingssupplementen/
But as you can see, still some very strange sizes..
Anything I can do here?
Many thanks!
Remco
]]>Hi there, when I try to regenerate my thumbnails I get the following error:
Unable to fetch a list of attachment IDs to process from the WordPress REST API. You can check your browser’s console for details.
When looking in the console, it says:
Regenerate Thumbnails: Error getting the total featured images count. Object parsererror SyntaxError: Unexpected token ‘<‘, “
<“… is not valid JSON
Please can you help? I am using PHP 8.2.
]]>Greetings!
I am a newbie to WordPress and am trying to understand how images work. I’ve found out that WordPress may generate lots of different sizes and load them each time it needs the specific one + requires more space. So I decided to remove any unused image sizes. For this, I found your plugin to see which sizes are currently being generated. It says:
Thumbnail Sizes
These are all of the thumbnail sizes that are currently registered:
thumbnail: 150×150 pixels (cropped to fit)
medium: 300×300 pixels (proportionally resized to fit inside dimensions)
medium_large: 768×0 pixels (proportionally resized to fit inside dimensions)
large: 1024×1024 pixels (proportionally resized to fit inside dimensions)
1536x1536: 1536×1536 pixels (proportionally resized to fit inside dimensions)
2048x2048: 2048×2048 pixels (proportionally resized to fit inside dimensions)
woocommerce_thumbnail: 300×300 pixels (cropped to fit)
woocommerce_single: 600×0 pixels (proportionally resized to fit inside dimensions)
woocommerce_gallery_thumbnail: 100×100 pixels (cropped to fit)The question is, how can an image have 0 pixels? When I visit my uploads folder it doesn’t have that kind of images. The sizes are 768×576 and 600×450 (for zero dimensions). Please, could you help me identify, why does WordPress says so?
Thank you for your time and efforts,
Yuryi
