simple roll over gallery

Hello
I am a beginner in building websites, using artisteer and WordPress. I am cherching for weeks for a simple roll over gallery plugin that allow to open in the same page: on one side a thumbnail, and when you pass the mouse over it, it open the large correspondant image on the other side. With the possibility of several thumbnails in columns.
There is a plugin i found :”image mouseover” but it doesn’t seem to work on my current wordpress site: no settings appears…Is there a solution ?
Thank you!
