I did some tests with the original frames to find out how much I could compress without introducing many visible artifacts. PNG quality was of course great, but would only reduce the original BMP size (roughly 550kb for a futurama screenshot) to 220kb. JPEG @ 100% was about 100KB, and JPEG @ 97% is around 70-76KB whereas the original JPEG @ 85% was 30-36KB. I believe the current shots are a good compromise between loading time and quality, the old ones definitely werent.
