Flickr Tags

Here is one of my mash ups from my project from last semester. I was using a database belonging to my research project. I was able to get Mysql-Python to work. It was fun. Now, though, I want to do a project that queries tags or a specific pool of photos in Flickr. Is this possible? I looked at the Flickr.py source code but I can't see where you are storing the tag-body information from Flickr, which is the "clean" version of the tags. Is this just the name or the id? And I wonder how you could specify to only query a certain group or pool of photos??

oh and by the way that photo is also using the WordNet library to make up the text, by looking at the tags of our photos in our database, wee!
