that's exactly what I meant (working around the lack of transparency support in IE) The site I am building at the moment, is going to have something along the lines "optimised for Firefox". As for the IE users, I found that giving them the equivalent JPEG is good enough.
Thanks for the links. I've tried most of this stuff. JavaScript is not on the cards though. I managed to achieve some filtering with CSS/XHTML, but the best so far has been, Firefox sees the PNG, the IE sees the JPEG but also the PNG, so I got fedup and now I am working to figure out implementing the TCL solution as advised by Dave.
Thanks a lot for all the advice.
