1. You created
a image like this.
2. You want
to place it on your web page, but it's not nice because you have a background
and don't like the white border around your image. You have to make the
white color transparent.
3. To do
this, select Tool/Color/Select color. Then click with the mouse
in the white area of your image.
4. Select
Destination is mask and press OK.
5. Now select Tool/Mask/Mask
to Alpha and save the image in GIF-Format. This won't work with jpeg-format,
because jpeg can't save transparent information..
