W3 Total Cache Image Service

Hello @lapg

I am sorry about the issue you are experiencing and thank you for your feedback.
Can you please share the website URL and share the image that you converted so I can check this for you.
Thanks!

Hi and thanks for your reply.
The URl is for an example https://web2d2.com/webbdesign/ and one image that is told to be converted is the top left one, of a smiling woman.
Also, during conversion my server gets totally overloaded. Is that the way it should be?

Hello @lapg

Thank you for the information.
I can see that some images are converted like https://web2d2.com/wp-content/uploads/2020/08/037-1024×758-1.jpg
Can you please check the source of the wp-admin and let me know if you are seeing any ajax requests repeating in the Network Tab?
Thanks!

When I click the link to the image you refer to I only get 404. And (I might be stupid), but that image is still a JPG?

Yes I can see admin-ajax.php?_fs_blog_admin=true in the network tab. Two times in the last couple of minutes.

Hello @lapg

Thank you for the information. Sorry here is the image URL. As you can see it has a webp extension.
This is a new service and there are a lot of requests to the API server at this moment, so if you have issues like slow processing, or “Failed to retrieve a response. Please reload the page to try again.” it’s due to the overload. The ajax requests you are seeing are trying every 10 sec or so and yes, this may cause that the server resources to hit the limit on occasion.
We are working on adding more resources to this and once again, please understand that once the update was released there were more than 300k requests.
Thank ou for your patience.

Of course I can understand that.
But could you please let me understand if I have to relink all images to make the extension webp the default instead of jpg? Since if I look at the example image you gave me, I still only see the jpg extension?
Or maybe I just don′t understand it all…

I had the same experience. It took forever and ever to convert just a couple of files, the user experience was confusing because I didn’t notice where the webp file was, and the (shared) server dumped me several times. I can’t sit up all day and evening to reloat the page.

Fortunately I was able to deactivate this particular extension. I probably made a big mistake to click on the convert all at once option.

Now I’m on hold awaiting an update for this plugin extension, or at least better advice on how to use it.

Hello @lapg

Thank you for your feedback. Please check the screenshot below. You will see that the extension of the image is .webp. this does not mean that all images are converted due to the reason I’ve shared in the previous post.
As I’ve said some images are indeed converted so once again thank you for your patience and we are working on improving this.

@sandalsand
As this is a new service, and W3TC has a lot of users, everything happened in a short time and there were a lot of requests.
We are working on an update and than you for your understanding and patience.

Sounds great!

The idea is perfect, and once the solution sticks to that and works, nothing could be better!

@vmarko, I have now reverted all images and will try again. If that does not work I will wait for next update of the plugin. ??

And also when I checked the image you show on the screenshot I saw jpg extension, not webp as your image show. Strange…

@vmarko today it went much better.
I can see that only 9 images still are converting and 8 not being converted.

But…I still see all my images as JPG? I have emtptied cache and reloaded page several times. Both in source code and media library I only see JPG.
Also if I search source code I cannot find webp?
Could you please try to explain this to me?

Hello @lapg

I’ve checked the page you shared in the previous post, and yes you are correct, now it seems that the majority of the images are served as webp (Check the screenshot provided and focus on the file Type column)

Thanks!

Thanks.
But please can you let me know where in source code or WordPress admin I can see the webp file extension?
Because otherwise it seems to me that images still are jpg anyway.
Hope you understand that I would like to see what has been changed.

Hello @lapg

Thank you for your feedback.
Once you visit the page, right-click and click on “Inspect” or simply press F12 if on PC. The developer tools will show up on the right side. Next, select the “Network” tab and reload your page. You will see a list similar to the one I’ve attached in the previous post.
If you click on the image you should see content-type: image/webp header which means that the image is serving as webp.
Just to be clear, W3 Total Cached does not remove the existing image or physically replace them.
The point is that the image is served in the webp format.
I hope this helps!

Thanks @vmarko for explaining a bit more.
Now I think I atleast understand it a bit more. ??
I never thought that my images would be replaced, but I did think I would be able to somehow see the webp images.
Would the performance be the same if I actually uploaded webp images to my website compared to your feature?
