I guess Andy is assuming that you know which bits of your second image 
are to be regarded as transparent by colour. I think if the image has 
transparency (like some gifs) then you can use the string 'auto' for the 
mask. If on the other hand you need to mask off parts geometrically you 
need to set up a clipping path.
