Tested frm.py --image from https://github.com/gulkily/v3/pull/130 against zenmemes.com, starting from a Python environment without Pillow.
The screenshot below started as a 2560 x 1800 PNG of the Tools page. Without Pillow, frm.py refused it before sending anything and said to install Pillow. After installing Pillow it resized the image to 2048 x 1440 and posted it.
