Ian,

It's possible to do, and relatively easy if you're writing ONLY for IE.
The trick, as ever, is to write browser-independant code.

The IE-only way is to use those stupid "visual filters" you can
apply to
images as of IE4 Well, while most of them were completely useless,
there's one that does what you want.

<DIV ID="MyDIV">
STYLE="position:relative";
height=100px;
width=100px;
filter:progID:DXImageTransofm.Microsoft.AlphaImageLoader>
<SRC="MyImage.png">
</DIV>


The browser-neutral way is to wrapper that in some JavaScript that
writes out the PNG in a standards-compliant browser, the hack in MSIE4+,
and presumably a link to mozilla.org in MEIS3- :-)

Regards,

Mark
