>JPEG 2000, JPEG XR, and WebP I investigated this problem. Not all browsers supports one of formats. I think it's better to has several kinds of pictures for one source of picture.
I downloaded your plugin [evaluation] and installed it on my test server. I enabled all the options and told it to run the task. I configure it to convert images to webp, how do I know it's done with the tasks? I ran it two hours ago and my sample product still has a jpg image.
I'm using 4.0 right now but I will be installing it on my production (3.6) server when I purchase it.
No errors in the log and just realized image uploading does not work at all. I try to add images to existing products and it looks like it did it, then I refresh the admin page and my photo is gone.
