One of the best things about my website and what WordPress is capable of is the Gallery and the tagging. I used to use Gallery2 which was like fighting for the limited benefit. WordPress allows it to be so much cleaner. Since a lot is not documented well I am going to post my experiences here. The most important part of the was the plug-in Matt’s Community Tags plugin. However, I had to make extensive changes to some of the code to make it do what I want. In the interest of GPL and community here is a copy of my modified plug-in.
Description: Very beta, in this version the intention is for this to allow a moderated community to aid in tagging primarily photographic content, image attachments and such. This is a GPL derivative of Matt’s Community Tags version 0.3. Admin menus enhanced and the custom taxonomy improved.
Requires: WordPress Version 3.0 or above
Note that I no longer use this plugin and my images are now strictly using built in WordPress functions with a few minor theme tweeks to display native information and I no longer tag people in the photos.
