does anyone know where i can get a script to make it so when i hover over a image it makes a iframe scroll up/down..?

Here's something like that: http://www.dynamicdrive.com/dynamicindex11/scrollc2.htm

This one shows text links to scroll up and down in the demo...but it could easily be changed to use images:
