bulk thumbnail crop

There are a few things that I normally do when adding new pictures and albums. I set the captions, rearrange the photos, and crop all of the thumbnails. Currently there are ways to edit all of the captions at once, and it's also easy to rearrange items. This saves an enormous amount of time. However, there is no way to edit the thumbnails, unless you do it one at a time.

I'd love to see an interface similiar to the caption management that allows you to edit multiple thumbnails at once.
