Paste PNG into files, much like pbpaste does for text.
And also copy image from clipboard from a file like pbcopy.
However instead of pngpaste > thefile.png, it's pngpaste thefile.png,
so one does not accidentally barf binary into the console.

$ make all
From source:
$ make all
$ sudo make install
Or with Homebrew:
$ brew install pngpaste
$ pngpaste hooray.png
... pastes an image to a file
$ pngcopy hooray.png
... copies an image from a file
Supported input formats are PNG, PDF, GIF, TIF, JPEG.
Supported output formats are PNG, GIF, JPEG, TIFF.
Output formats are determined by the provided filename extension, falling back to PNG.
It's unclear if EXIF data in JPEG sources are preserved. There's an issue with pasting into JPEG format from a GIF source.
