Peter! You'll probably already know this page:
http://msdn.microsoft.com/workshop/author/filter/reference/filters/alphaimageloader.asp The element to which this filter shall be applied must have layout.[1] The filter will not create an background-image. The filter image lies behind the background, so you have to set the background-color to transparent and disable the original background-image too. Ingo has also made some affords to document this property: http://www.satzansatz.de/cssd/tmp/alphatransparency.html > Has anyone yet taken the logical step of writing a behavior.htc that > incorporates this solution? There is a htc for img-Tags. http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html This may be of interest too: http://www.pi-phi.de/t3v4/55.html (german) But I don't know an unobstrusive JS solution that automagically corrects the behaviour of IE <=6. Maybe Dean Edwards has something like that in his IE7 scripts? Ingo's doc is probably the most complete. I hope you'll have some time to extend that ;-) regards, Martin [1] http://www.satzansatz.de/cssd/onhavinglayoutrev07-20061019.html on Friday, April 13, 2007 at 13:15 Peter-Paul Koch wrote: > Hello, > Yesterday I talked to a web developer who passed me a technique for > using semi-transparent PNGs as background images even in IE6 and > lower.
