To expand on jboardman's suggestion, if you have no more than 256 colors in your image, then you can save it as a transparent GIF or even a PNG-8. Sadly, IE6 out of the box does not support PNG-24 files. You can still save down to GIF or PNG-8 if you have more than 256 colors. Dithering may occur, but as long as you don't mind lossy compression that still looks good, this is a perfectly good option.If you MUST keep your image lossless with transparency, you will have to either ensure that your audience uses IE 7 or use JavaScript to force transparency (see Xithis's message above).Kevin
