Regenerate image field thumbnails

[a-ok]

I ran into an issue on my server with the PHP GD library and all my thumbnails on image fields are now transparent (see attached).

Is there a way to regenerate these thumbnails without re-uploading all the images again?

What exactly is / was the issue?

Are the thumbs variation files missing or residing corrupted in the filesystem?

They exist physically but are corrupt.

Hmmm, there is a new action for PageListerPro (https://processwire.com/blog/posts/processwire-3.0.121-core-updates-and-more/).

If all your variations (thumbnails and other variations) are corrupt you can delete them with the Pageimage Remove Variations module. The variations will be recreated next time they are requested.

Yes this fixed things. Thanks for the heads up. I guess it's no drama if it removes variations of ones that weren't corrupt, right?

If you have inserted any variations into CKEditor fields it would pay to check those because they won't be automatically recreated when the page is loaded. You'd need to call the image sizer again with needed dimensions, either using the CKEditor image modal or via the API.

That's fine I don't allow for image insertions on text fields.

Thanks again everyone for helping me resolve this.
