PNGs do not write correctly on windows

[victorklos]

Found out that PNGs do not write correctly to file on windows, at least not on vista. Solution is to change file open flags to "wb+" in method write(), as follows:

def write(io_or_file=@@file_name)
  return io_or_file.write(fetch) if io_or_file.respond_to?(:write)
  open(io_or_file, "wb+") { |io| io.write(fetch) }
end

thanks to the clear explanation of why the PNG header is like it is on wikipedia.

Cheers, Victor
