You cannot use image.php?u=$user[userid]. That is only valid if the avatar is in the database, not filesystem (and it's not complete at that - you should have &dateline=xxx on the end of it).

Take a look at the $posts query in showthreads.php around line 989. Look at the way the customavatar gets included. You need to include that in part of the query in showgroups.php (which is going to be a bit difficult since there isn't a hook to use). Then look at class_postbit.php, the function preocess_registered_user() where the avatar gets processed and $show['avatar'] gets defined. That is the sort of thing you will need to put into your code somewhere.
