<img name="bob" src="bob.gif" onMouseover="over(this)">

I like the idea of wrapping the .src change into a function. When there's lots of rollovers, that eliminates some decent file size.

Note: your code above works fine for Explorer, but other browsers don't all support an onMouseOver event handler unless it's inside an anchor tag.
