i hacked this to work with "joomgallery" extension so i could tag the pictures with a specific tag taxonomy and it works great. the interface is very easy-to-use. but my "single select" tag choices are displayed in a multiple-choice dropdown which was annoying (it may be b/c of my custom tweaks).

i wish they had a frontend interface to manage just the tag definitions. but all-around great product.

i hacked this w/"Custom Properties" extension so i could have a specific tag taxonomy to tag the pictures with and it works great. it has a lot of useful features, and their forum support is good enough. it does not render perfectly in ie6 with some joomla templates.

still waiting for Cooliris-enabled search results and frontend java uploading capabilities!

i used this in conjunction with "module for Admin-User-Access and custom toolbar" and "module for Admin-User-Access (frontend)" and it works great.

i just wish all the features were free!
