Perhaps it was a misinterpretation on my part. All I meant was that I do not need to look at the images through any of the standard tools (ie, via show()). For my purposes I need to write the image to stdout (not to disk) in its binary form - which is what I do now after modifying some stuff in backend_gd.py.
