Transparent areas of graphics turn black

Problem

PowerPoint turns transparent areas of images black.

Solution

A visitor to the PowerPoint newsgroup reported a solution to this problem. He'd created PNG graphics in Photoshop 6/Mac and found that if he turned color management OFF and chose the option to "Discard embedded profiles" when saving files, the problem disappeared.

PowerPoint newsgroup regular Adam Crowley tells us that you can remove a colour profile from a specific image in Photoshop by choosing Image, Mode, Assign profile, Don't colour manage this document (or Edit, Assign profile in Photoshop CS/2). This should also solve the problem.

Adam adds:

If you have PPT pre-2002 and a presentation with problem images but not the original image files, this doesn't help much. Try using the transparency wand on PowerPoint's Picture toolbar to turn the black pixels transparent.
