I need some basic HTML help.

I *finally* figured out how to put in an alt text tag on an image, so
the name of a picture comes up when you mouse over an image.

BUT!

It only works in MSIE's browser, not Safari and Firefox, which leaves
out some visitors.

Any help? How can I get this feature to work in every browser (or is
that impossible?)

I wanted this feature for the index list. Please see http://www.csnjc.org
