There is a better workaround since we have true transparency for web
images. It has the disadvantage to only work with simple backgrounds,
there are two layers: one with your image an one with the (simple)
background of the webpage.
Then "alpha -> selection" and save the selection into a channel.
combine the two layers.
invert the selection (after you get it back from the channel) and cut the
Then you have a simple alpha, a region where the alpha fading is combined
with the background and the picture.
Now there is only the problem to convert the RGB image to indexed. The
advantage: There is no border between the image and the webpage background
(sometimes image colors are different from the same colors in images).
right now the web page is in german only
but this will change as time goes by ;-)
