Diversity in Stock Photos

Another thought: based on the linked article it sounds like many of the photos in the Articulate library may have been tagged by the photographers, and those tags may or may not match what the photo is actually of. What about letting community members add tags to photos? Or even just adding "categories" by selecting from a defined list? I understand if we don't want someone coming along and adding a tag of "Kristin's favorite" to a given photo as that is not useful to anyone else and too much of that would potentially increase the database size too much, but a defined list of attributes may be helpful, and then you can get the community to assist. 

Also, allowing individuals to tag favorites is maybe a good idea. Or not, not sure how that would affect Db size.
