<br></blockquote></div><br>My goal is not so much opacity, but the display of a PNG image with a full 8-bit alpha channel (i.e. variable opacity/transparency). As far as I can tell IE for Windows (prior to v7) does not display 8-bit alpha, only 1-bit simple mask ala gif files. However, the technique I described in my previous post does allow IE (
5.5 and greater) to display such images correctly. Why MS never put that capability directly into the <img> tag I don't know.<br><br>Thanks for the tip though.<br clear="all"><br>-- <br>Allister
