Thread: mouse over and iframe

Hi, a while ago there was a very useful thread concerning this subject.I cannot find that thread anymore, a member had explained perfectly how to do it.From memory I did whatever I recalled, only problem, the larger image in the i frame only changes when i click on the icon, nothing happens with mouseover, although on the events page i did choose mouseover.
Also on the events page, not sure what the target is supposed to be.
Anybody can help please?
