Images displayed before Username for certain Usergroups

[Brexen]

Hi Guys,

I need to know if there is a plugin out there, that allows me to set an option to display an image before the username; if a user is in a certain usergroup. If not, how would I go about creating one, so it displays everywhere on my forum?

I know this can be done with HTML Mark-up, but I want it done my way, so that the HTML Mark-up of this group, don't interfere with other Usergroups.

Example: A user can be Premium and apart of this group with the image still displayed left of their username, without affecting the username colour.

Any help is appreciated.
