Access users avatar

[Python2]

I am creating a dynamic script in PHP which will be called like this...

mytag.php?id=xx

where xx = a users id.

Basically what this scrupt does is get that users data like username, post count, join date etc and using GD it appends it onto an image and the displays it.

Im fine with that part but what I want to do is to also show the users avatar on the generated image. All my users avatars are stored in the file system but I cannot figure out how I access them in the script...

In what table are the file names stored? What column?

Thanks

Anyone?
