How do I fix the image size issue when switching to responsive theme?

  • I have been running my site for over five years, and havea bout 2100 posts on it.

    The standard image size Ive used for all this time, has been “large” which has been set in the WP settings as being 500px – so whenever an image is put into a post it automatically goes to that.

    Now, Im moving over to a responsive theme … and 500px is too small. I changed my settings to Large “800px” and this works perfectly for all of it .. going forward.

    Unfortunately, all those 2100 posts in the past, now have tiny images that dont work with the responsive theme.

    I tried one thing, and that was making sure the new “large” size was set yo 800 px, and then ran the “force image thumbnail” plugin to see if it would then regenerate all those images ..

    Unfortunately, as soon as I did that, sure, it seemed it fixed the thumbnails,, but in the process all the image links seemed to break – I stopped it really quickly. It seems that it could no longer find the image size of the thumbnail, as well, it didnt exist any more. It didnt actually change that size of the images in the actual post. When I went in to edit an image, I could see that the *selection* was now for large “800px” and I could choose that and then get the correct images, but yeh …

    tldr: 2100 posts, new responsive theme, need to work out how to resize all of them in the posts from “large ” that was set at 500px to “Large” now set at 800px.

  • i’m afraid you may have to edit each and every post manually. I guess its almost impossible to fix all images dimension at a time.
    if you don’t mind can you plz share your site url with us?

    Hi,

    You should be able to just run a thumbnail rebuilder, personally I use https://www.ads-software.com/plugins/ajax-thumbnail-rebuild/ whenever I need to do this.

    Hey Sam -0 it is https://www.invurt.com … not on responsive theme until I can work this out. Manually doing this isnt an option … theres 2100 posts and it’d take me a year to do them, there has to be a solution whereby you can just change the image size and run something to actually rezize them in the page?

    Marius – as I mentioned in the original post, I have tried two different thumbnail builders and it has not solved the problem, it just breaks the images in the page and they dont display. Or are you saying that the Ajax builder will fix this issue?

    Marius – the Ajax thumbnail resizer didnt work, as you can see, it just broke the image

    Hi,

    It almost seems like your system isn’t capable of writing new sizes of the images. Have you checked your error logs to see if there’s anything there, as there appears to be something strange going on here?

    Hi Marius, I have gone through the error log and I dont see any WP errors that correspond with this – in fact, there are no errors or the dates that I ran the plugins at all.

    Any other ideas here?

    If you upload a new image, does it get the correct sizes ?

    yes, if I upload a new image, the size is correct – its just all the existing ones (about 10,000 or so) that dont resize =/

    This is very strange indeed then, when you are resizeing them using the plugin are you telling it to resize just some sizes, or all of them, it might be worthwhile to tell it to only do individual sizes at a time if you have that many media elements, or maybe even using a command line tool if that’s available to you.
