Rank Image Order
 

Hello,

Together with a friend I run a gaming clan and use VB as a forum. Because the clan is semi-military themed we make use of a military rank structure within the clan which I operate using Vbulletin's User Rank Manager in combination with usergroups.
What I do is create a rank, create a usergroup and link the two together. Whenever a user then is that rank I assign the usergroup as a secondary usergroup so the rank image appears on his/her profile. I have no idea if there is a much easier way of doing this, but it seems to work for now.

However, now I have run into a little problem. It obviously works fine with just 1 image, but I want to add a second image next to the rank image and particularly on the right side. But when I make a new usergroup and new rank for this image and give it to a user as a sort of third usergroup, the rank image appears constantly on the left.
My question now being, what variable decides how rank images are ordered? Usergroup ID, filenames, order of creation? If anyone could help me out with this one way or the other it would be most welcome :).
