Using M-x set-background-colour RET and you'll see the background of the image changes with the background. Now use 'convert' from ImageMagick to make a copy of the image: $ convert Tango-Palette.png Tango-Palette-copy.png Open the new copy in Emacs and the transparent pixels show up as white pixels. Open the copy in The GIMP or gqview and you can see that the background really is still transparent.
