I want to add that the PNG preserve its full alpha
capabilities, though it had been grilled by this 
lossy compression. Means I can put something under it and
this will show through. I can even animate 
the whole thing, continuous transparency still works.

Mawe,

Mark is completely right- SWF knows JPEG and
"lossless/zlib" compression. If there is any other
format it must be new and unknown to me 

As repeatedly explained by Ralf in this thread, an alpha
mask with JPEG-compressed images can be achieved with the
mask="..." attribute. Swfmill doesn't provide any
automatic conversion (like the Flash IDE obviously does);
that was a design choice to keep the dependencies (and
license problems) low.
