Deleting WordPress Generated Images Breaks Media Library

  • After tracking down huge bandwidth use on my host to WP’s default multiple image generation (which I have since disabled by zeroing the Media Settings), I started deleting all the unwanted WP generated image files, leaving only those that were originally uploaded for posts.

    While deleting (via FTP) the largest of each of these multiple files, I noticed that doing so “breaks” the associated thumbnail in Media Library. If I re-upload the same file, it restores the missing thumbnail, so I know that is the cause.

    Is there any way to display thumbnails in Media Library without having to keep these huge files on the server?

    Have you tried leaving the thumbnails of that particular size in place?

    Thanks for responding. Yes, that was the first thing I tried. Surprisingly it has no effect.

    This plugin claims to help with the reduction of unnecessary images, but I have yet to actually test it thoroughly:

    Thanks for the link but I’m not sure what the plug-in is supposed to do. I installed it and clicked on “Start clean up” (it adds a button under Media > Settings), but it didn’t seem to do anything.

    Although it claims to “clean up all of the image sizes that were generated for your existing media”, there were no file changes that I could find. It had no effect on the missing thumbnails, either.

    That plugin is supposed to do what it apparently does not, and I had certainly not mentioned it so you would test it for me.

    There might be some kind of media manager plugin that can do what you need, but I would not know which one to suggest. One thing I do know is that you could download an uploads backup and then cull from it the extra images, then delete all images from your Media Library, then Filezilla-FTP-upload them, then use the ‘Add From Server’ plugin (and “Current Time”) to register them in the library after setting your crop sizes to zero (0) since your testing seems to indicate that could work. That could be a lot of work if you have many images, but their links would still be the same so they would be found by pages and posts. However, I would first try just one or two to be certain that actually will work.

    Thanks …there are hundreds of images on the server, but as I haven’t found a plug-in compatible with WP v.4.2.4 that actually auto-deletes the resized junk, I may have to remove them manually anyway. If so, your method sounds like a possible solution. I’ll try it out first as you suggest and then get back to you.
