Transparent PNG Issues

Lectora already publishes PNGs using those parms:filter:progid:DXImageTransform.Microsoft.AlphaImageLoader( src='%s', sizingMethod='scale' );So you really aren't getting anything that Lectora doesn't already perform for you. We also add:filter:progid:DXImageTransform.Microsoft.Alpha(opacity=0);We have found this fixes the transparency issue for most PNGs in IE except for:PNGs in grayscale with an alpha channelPNGs with a background color and an alpha channel.Haven't found a viable workaround for either of those issues.Tim V
