	You can do this with IE5+ like so:

document.images['name'].src = "image.gif"
document.images['name'].alt = "move right"

Comments:
* In theory, this should work in IE4 also, but there is a bug that prevents
the alt-text tooltip from being dynamically updated (if you check the "alt"
property via script, you will get the correct value; however, the mouseover
tooltip does not reflect this).

* This *won't* work in Netscape 4.x and earlier, which does not understand
the "alt" property (it returns "undefined").

* Netscape 6 *does* recognize the property, although the latest Mozilla
builds (on which Netscape 6 is based) do not display any tooltips;
presumably this will change by the release version.
