Well I couldn't upload the file I was playing with since it is a copyrighted logo, but I made you 2 new files (gif and png)
Have fun!

Hm. It seems that GD's handling of pngs with transparency is broken, If you just load the png and then write it back to a new file, the transparency is screwed. Replaced by black. Doing the same with the gif version worked okay.
Whether the fault lies in GD; or the underlying libgd; or the libraries that underlie that is questionable. But given that libgd seemed to have died a death, I guess it's time to move on and find something else that provides similar functionality without requiring your conversion to O'Woe in order to use it.

The difference is that PNG uses an alpha channel for transparencies while GIF just sets a certain (and single) color to be transparent. GD just seems to ignore the alpha channel in a PNG file so when a pixel is (0,0,0,0), it just reads the first 3 value which result in a black pixel.
Do you know another module for manipulating images? Besides ImageMagick that is.
