Rehash of #503. Currently uploading very large images can cause the following error:

This can be resolved by adding a configuration option to change the PIL constant PIL.Image.MAX_IMAGE_PIXELS.
I'm not sure if the FFMPEG limitation noted in #503 still applies, but I think the option should be exposed either way.
