IE 5.0 should be fine. Haven't tested it with 6.0. I don't even remember
which sites I've used that code snippet at. If I can rustle up some, I'll
let you know.

It should. The function "F_loadRollover" is called with "onLoad" event for
the target image. This is one of the weaknesses of this script. You have to
not only use the onMouseOver, onMouseOut events - you also have to use the
onLoad event, for each Image. This can create a lot of HTML clutter. The
"F_loadRollover" also builds a "public array" of all the roll over images
for use by "F_roll". Not sure of the memory hit taken by this on a page
with a ton of roll overs.
But on the other hand, you are embedded the logic right into the target
images. This might be "better" from a construction stand point.
Hope this helps.
