I haven't played with IE6 and I'm amazed if it's lost support for the img alt attribute! All those sites that have put time into creating an accessible website...

Anyhoo... you could always try the title attribute - this should work with all HTML elements giving you the attributes contents as a tooltip on mouse over. i.e:
<a href="blahblah" title="Click here to go to blahblah">blahblah</a>. It is part of the W3Cs recommendations and it's supported in IE5+, and NN6 as far as I know (probably Opera too at a guess).

Normally the title attribute doesn't work in <img> tags as you're supposed to use the alt attribute - you might want to try it though.
