the syntax is correct, but i looks like your image is not correct.

You need an image with "real transparency" in it.

The engine does not compute irregular shapes from a b/w image.

It just needs an image with transparent areas in it.

So look if your favourite image editor allows defining transparency in
your image and then save it as a GIF or 8bit PNG.

Drop a line (offlist, if you like) and i send you a small example/more 
info/assistance.

Hope that helps.
