[jQuery] Changing part of a URL path with JQ on hover?

[ldexterldesign]

Hey guys,

I have a image rollover I need to do through JS (I don't think it's
going to be possible through straight forward CSS. The practicality is
I'll have to put an extra class on all the images to make them
reference'able)

I have this:

$(document).ready(function() {
   $("#accreditors a").hover( function() {
      // change part of the url path;},
      function() {
         // revert the url path back to normal;}
         ); }
      );

Any tips or functions you can throw my way, or will I have to go at it
and handle the string?

Thanks,
L
