Additional Usergroup Image Problem

Hey.

I'm testing a forum and i've installed the ougc additional usergroup image plugin just to check it out. My account is in 3 different usergroups. One is the admin group and the two other groups are test1 and test2. Admin is obviously the primary group.

When i'm displaying Admin (my primary group) as my main group, the plugin does show test1 and test2 usergroup images on postbit and profile but when i change my display group to test1 for example, then the Admin image gets removed from both postbit and profile as the plugin shows only additional groups and if i change admin to additional group, i will lose its features and powers.

What should i do to show my primary group image on postbit and profile when i choose an additional group as my display group?
Like this: linkz's primary must be Admin but is still showing in the additional groups.
