Oops, read on and saw that the OP already had this covered - in which case I would refer to David's reply below!
Sorry about the confusion,

Tobi,

Just another thought to throw into the mix...  What if you made an 
"empty" bitmap with a transparent background color?  There are some 
tricks to doing this, you have to fool around with stuff like "Use 
Source Color Key" and "Source Color Key".  I don't have a lot of 
experience with this myself, but if you search online with those 
sorts of terms, or look at the ImageDisplay.SourceColorKey topic in 
the online E-Basic Help, you might get some ideas.
