FWIIW, I took a screenshot, saved it as a 16 bit BMP, then converted the BMP as a GIF, JPEG, and a PNG. While very unscientific, this says BMP with gzip is a winner for two reasons:

1. It is similar in compression ratios to PNG and GIF
2. We already know how to gunzip and BMP.

Benchmark: 495410 screenshot-16.bmp

25411 screenshot-16.bmp.gz 25875 screenshot-16.PNG 37727 screenshot-16.GIF 148854 screenshot-16.JPG

(Trivia: I did JPEG because it was there. It is generally a poor choice for splash screens because it has artifacts on sharp transitions, which splash screens tend to have.)

This seems good! :)
