Hi,

i've "hacked" a quick demo for you here http://ghostwheel.de/demo.html.

i'm think it currently only works in Mozilla and IE>6 ... but i've not tested it.

If Javascript is enabled you can clear the alt/title tags by pressing "clear tags" - this should be done onLoad - but it's only a demo ;-)
"show alt tag" and "show title tag" display the image's alt/title

the "NOSCRIPT" is for browsers without javascript.
