Usergroup Conditions (Postbit_legacy)

[Frost5]

I'm still learning the in's and out's of conditions and have run into a problem. I plan on using a condition statement for my usergroups, but I cannot piece the codes together to create a successful outcome.

Basically, I would like to have a image appear in the posbit_legacy template, depending on what usergroup you are in.

Are any of the following codes close to what I need to achieve?

<vb:if condition="is_member_of($bbuserinfo, 1,2,3)"> </vb:if>

Would I need to include an image source in that code too?
