Image In Postbit For dditional usergroups

[lolzers]

I have the following code, how do I make it so when a user decides to join one additional usergroup, that an image shows up in there. I have the following code, but it isnt working.

<if condition="is_member_of($bbuserinfo, 93)"><img src="imagesource" alt="althere" /></if>

<if condition="is_member_of($bbuserinfo, 90)"><img src="imagesource" alt="althere" /></if>

<if condition="is_member_of($bbuserinfo, 92)"><img src="imagesource" alt="althere" /></if>

<if condition="is_member_of($bbuserinfo, 91)"><img src="imagesource" alt="althere" /></if>
