Custom Icon over nameplate

[Turczyk]

Hi i wanna know if it's possible to make an addon that show an icon(or texture/image) over a nameplate of a party member. I dont care if its hardcoded the party members names in the code.

I m healer and i want to keep tracking my friends over the screen. And that its not always possible because sometimes i m not the leader of the group.

This addon do something similar but with the target: http://www.wowinterface.com/download...Indicator.html
