It's a bit of a sledgehammer, but you can use the GIMP to do this - open the image, right-click on it, Layer -> Transparency -> Color to Alpha and choose white as the color to convert to the alpha channel. [You might have to add an alpha channel first - I don't remember.] Ben -- Ben Stern UNIX & Networks Monkey [EMAIL PROTECTED] This post does not represent FTI, even if I claim it does. Neener neener.
