rollover change pictures

My site
currently dosent seem to be able to do the thing where it will change pictures if you move the mouse over it.


<td colspan=1 rowspan=3 width=232 align="center" valign="middle"><a href="#" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Guard Plate','','http://www.geocities.com/legocomputer2002/GuardPlateDown.JPG',1)"><img src="http://www.geocities.com/legocomputer2002/GuardPlateUp.JPG" alt="Guard Plate up and down rollover image" name="Guard Plate" width=232 height=174 border=0></a></td>

The image names are correct, but it does not want a new picture to come up when the mouse rolls over it.
I hve tried looking at different places, but they are radically different, and i have no idea if it is even in HTML.

Thank you in advance

 

Most image rollovers use javascript to perform the flip.

You can read a good tutorial here:

This site it actually great site period for learning how to design web pages.

 

Thank you. Got it all fixed. I tried to use it from another website, and i think something was different. The site is awesome also.
