Tracking/Conversion Pixels on Facebook

Hey All-

Was wondering if anyone knows how to implement a simple image pixel on Facebook Fan pages. Say someone 'became a fan' of a group I set up and I wanted to track them via an image pixel so I can populate associated data in my systems. How could I do this?

It is tricky because it seems as though you can't SRC your own hosted images or place any lines of code.

Any suggestions? I need BHW force on this one!

Thanks,

Doesn't necessarily need to happen on the wall.... just needs to happen somewhere after I send the traffic through to FB.
