[IAEP] Any ideas how to make an image with a transparent background inSugar?

[Bert Freudenberg]

About how to get the drawing out of Etoys:

Drag-and-drop it into the Sugar Frame's clipboard, or just press Ctrl- 
C when its halo is showing.

Then either insert into the activity you want directly by drag-and- 
drop or Ctrl-V (if the activity supports that), or store the clipping  
in the Journal via its Frame clipboard icon menu.
