Is there an installable PHP/MySQL image database system like Picasa? I want to setup a small image database for our company.
It would be hosted online, so the co-workers have access from any place. I dont need the complete features of Picasa, simple storing, tagging, preview (with thumbs) and download (maybe as ZIPped packages) would be sufficient.
EDIT for clarification: Actually, I am neither searching for a photo sharing service like flickr nor for a gallery. Although it should be possible to use the both of them in a way I'd like to. Well, I am not really sure.
The truth is: I already had coded a system for myself. But this was years ago and far from state-of-the-art. It works, but it is not very user-friendly. That's why I'm searching for an alternative.
