Code to load PNG

[jdarling]

I'm planning to make a standalone MiniPNG unit based on Imaging's PNG handler so there is still hope
I guess only loading of PNGs is ok (no saving)?

Loading would be excellent if absolutely NO (as in 0) 3rd party libraries or etc are required! Creating, Saving, whatever is easy enough. Loading the lil buggers is a real problem.

At least, that's my opinion.
