if i have a DIV class with a background picture (div.background), and i would like to make a link to swap that picture, would this be correct:
<a href="#" onClick="this.style.background='white url(bg04.jpg) no-repeat'">

Its not working, and i cannot figure out why, you can see it here:

any help would be much appreciated

nevermind, i dont know what i was thinking.
all i had to do was give the div class an ID and modify the eventhandler:

<div class="background" id="swap">
<a href="#" onClick="getElementById('swap').style.background=' white url(http://www.brycepetit.com/bg04.jpg) no-repeat';">
