I think it would be a good idea implement some sort of picture gallery as an asset field. It would be nice to be able to create an asset called "Site Photos" where I can upload many different pictures, and even have these photos separated by folder "ex. rack1 photos, rack2 photos". This way a user can easily click on the site photos asset, then on rack1 and then they can view an entire gallery of the photos uploaded. Sometimes it's nice to have these site photos for documentation.
