That's wonderful thank you. It seems to work perfectly.
FYI I implemented it like this:
transparent_gif = StringIO("GIF89a\x01\x00\x01\x00\x80\x00\x00\xff\xff
\xff\x00\x00\x00!
\xf9
\x04\x01\x00\x00\x00\x00,\x00\x00\x00\x00\x01\x00\x01\x00\x00\x02\x02D
\x01\x00;")
def get_transparent_gif_response(request):
return BaseResponse(wrap_file(request.environ, transparent_gif),
mimetype='image/gif')
