22985,Edit thumbnail image only - loses all sub sizes in attachment meta,lewismcarey,markoheijnen,"I have several additional image sizes in my theme. When I crop an image and save over only the thumbnail, all references to the various sub-sizes are lost and only the new thumbnail is referenced in _wp_attachment_metadata.

1. Add an image to the media library.
2. Output _wp_attachment_metadata.
3. Edit the image (crop).
4. Save only the thumbnail.
5. Output the relevant _wp_attachment_metadata.

This may be an issue with wp_save_image() not re-genarating subsizes from the original.
I believe this to be different from Ticket #19889  as it appears to remove references to default sizes from media settings screen.",defect (bug),assigned,high,3.5.1,Media,3.5,critical,,has-patch,bananastalktome@…
