Track Facebook Pages

I have a FB Fan Page and I would like to track this page.
Is it possible to track Facebook Pages with Piwik?

It should be possible using the Piwik Image Tracker. More details here: http://piwik.org/docs/tracking-api/ .

Is it working correctly? I thought there are some problems because of the caching of Facebook.

I am not aware how a cache would cause an issue as the image is called from PHP. The only way to know for sure is to test it out…
