How to set the background color of the illustration in the slide to transparent. Make sure that your picture is not in GIF format. (GIF is composed of multiple pictures. When setting the picture background to be transparent, it will only work on the first picture.)

(You can hover the mouse over it and the tool name will appear after a while.) Then click on the image to remove similar colors. This tool in PPT can only remove one color at a time. If you want to remove more colors, you can use other graphics processing software (photoshop, flash) to process the image and change the colors you want to remove into solid colors. This way it can be removed at once in PPT.
