Does anyone know of a way to create a datasheet-like view for a photo library
easily? (Or some tool/web part/add-on that will do it?)

Our public relations department has loaded 4,000+ photos into a site and now
needs to tag them (keywords, description, etc.)

In a perfect world I'd like them to be able to enter text and see a thumbnail.
An ok solution would be the file name and the fields they need to edit.

I can make a custom view or do something in visual studio if I must but before I
went to that trouble I thought I'd check here and see if anyone knew of any
quick ways to do this without custom work...
