This is what an avatar image looks like from postbits

<img src="image.php?u=100&amp;dateline=1309261189" alt="JoeBlow's Avatar" title="JoeBlow's Avatar">

I think you could leave out the dateline, I don't even know what's that's for. The alternative would probably to run a query against the avatar table to get avatarpath. I think you would have to do such a query for each forumbit.

To get a username and userid I think you'll need a plugin in "forumbit_display"

	$forum['lastposterid'] = $lastpostinfo['lastposterid'];
	$forum['lastposter'] = $lastpostinfo['lastposter'];

So an avatar would look like this:

<img src="image.php?u={vb:raw forum.lastposterid}" alt="{vb:raw forum.lastposter}'s Avatar" title="{vb:raw forum.lastposter}'s Avatar">

You may have to experiment around.
