so i made these: (i know the backgrounds aren't transparent)

-Normal
- Mouse hovering over
- Pressed.

and i want to make a script that i can open with firefox or chrome or whatever, so that when i rollover the image it goes to the second picture, and when i click it- well, you get the idea. i tried googling it but it's a bit too complex in the way they explain it. anyone here know how to do it and explain it simply?

btw, i think this thread is in the right place. if it isn't then could a mod please be nice and move it?

Thanks all! :D
