[pygame] Mask

[Kris Schnee <kschnee@xxxxxxxxxx>]

I wrote a program that does steganography... to get an idea of what it 
does, see http://kschnee.xepher.net/pics/darwin-source.png -- the source 
code is embedded in this image. A copy of the Bill of Rights is at 
http://kschnee.xepher.net/pics/bunny.png .

Only problem is, I can't distribute it as an EXE, which most people will 
need to actually use it. I'm using the Python Image Library rather than 
Pygame this time, for the sake of PNG file support -- a resonably common 
Web graphic format that's lossless. The EXE crashes with the following 
error:

> > > File "Image.pyc", line 1745, in open
> > > IOError: cannot identify image file

Last time I asked, in a vaguer way, the response was:

> > > Is there a libpng/libjpg in your dist directory?  That might be it.

But:

> As far as I can tell, no. In fact, though I remember reading that PIL required ZLib to run properly (http://www.pythonware.com/library/pil/handbook/formats.htm), my list of downloaded files doesn't show that I ever downloaded it! Does this mean I should download and install it, then pull some file/directory out of it and put a copy in the dist directory of my program, even though it apparently runs as source code without the library?

Any ideas? If I can get this thing working I'll distribute it. I could 
even post a link to the source code first.
