image roll over

[juan casal]

Hello!
I'm designing a website that has a few images that I want to change when the mouse roll over.
The images aren't project thumbnails and either have links. There are just simple images.
How can I make them roll over and change for another images?
(in other words, how can i do the thumbnail roll over but not been a thumbnail?)
Thanks!
