When I go to Settings -> Media, I noticed a lot of settings for thumbnail generation for different sizes, this is consuming a lot of inodes on my hosting, so I was wondering how can I delete them and stop them from generating. And also, will stopping them from generating have any affect on the website? I tried going to functions.php and copying the recommended code from Add Custom PHP to theme option in the media settings, but that did not work
PageSpeed doesn’t register any custom sizes. In fact, if you use dynamic thumbnails plugin that we recommend, custom thumbnails are generated only for the featured images.
