Dreamweaver PNG problems

[internetfixes]

Recently I've decided to change from using GIFs in my website to using PNG. However when I optimize the image in image ImageReady and insert the image into a layer in Dreamweaver MX it losed its transparency. All that remains when I preview it in my browser is the image surrounded buy a light blue border. Is there a way to rectify this problem?

Thanks

Welcome to WebmasterWorld!

PNGs lose transparency, even binary transparency, when used as a background in Internet Explorer. The stated solution is to use the proprietary MS filter.

Binary transparency works fine when you insert the image in an <img> tag instead of with a style. Alpha transparency requires the same filter as above.
