this is my first question, so forgive me if it is not perfect 😅

I am asking, if there is a way, to completely disable and remove the thumbnail functionality from WordPress. (I am using an image CDN plugin, which is taking care of resizing, optimizing, etc. So, no need for the extra size and file count consumption by thumbnails)

I already know how to prevent WordPress from generating thumbnails, good so far. I also know how to delete all thumbnails (from the filesystem). But doing this on my staging environment brought up 2 obvious issues I forgot about.

To prevent the issues, I would need functions, that:

Removes all thumbnail information from the WordPress database (i guess postmeta?)

"Replaces" the image size Settings, of all images used in Blog-posts or Pages, by "Full Size"

"Replaces" the thumbnails, used by the media library, with the full-sized image (since I want to delete all thumbnails)

Thanks in advance
