I can't claim that recursive layout to myself... if you look at the
$(element) function in the prototype library (http://prototypejs.org) it
is laid out the same way. I just didn't understand why they had done it
that way, due to my lack of understanding of closures! Once you guys
helped me understand closures a bit better, I realized I could do my
function the same way as the $() function.

Using a simple HTML solution might have made sense had I realized that
"title" worked the same way as "alt" in the first place, but at this point
I had already written the JS code. :-) Not only that, but this method
allows me to style the tooltip div however I want. For instance, I could
change the font size / color / background to show a more critical message
on hover. Another _small_ gripe I have about using alt and title is the
amount of time it takes for the tooltip to show up once you are hovering
over the element.
