Javascript link for multiple iframes

[onlymu]

I'm trying to get a single link to update three iframes...

I swiped the quoted bit off of another webdevelopers' forum.
However, it was used for links on a drop-down menu (my link is an image). I know no Javascripting, so I'd just like to figure out how into integrate this into my website. The first bit goes into a <script> tag (I think, correct me if I'm wrong) but where would I call the function? In the href of an <a> tag around my <img>?

Code for javascript linking to multiple <iframe>'s uses this function:
function loadFrames(frame1,page1,frame2,page2) {
eval("parent."+frame1+".location='"+page1+"'");
eval("parent."+frame2+".location='"+page2+"'");
}

The code to activate the multi-links is:
url=javascript:loadFrames('FrameA','http://www.google.com','FrameB','http://www.yahoo.com')
This could easily expand to however many iframes you need!

Alternatively, if you give me another workaround for this, I'd greatly appreciate it. Thanks.
