If you want to add multiple mouseovers, keep adding on more of the code into the script, but remember to change the #.
Add the following script wherever you want your mouseover to be.
[a href=BLAHBLAH.html onmouseover="image0.src='name-of-mouseover-image.gif';" onmouseout="image0.src='name-of-original-image.gif';"]
To add that second mouseover, use the same code, but change the 0 to 1.
