Please do not use png, I do not have any software on my machine that
will read them. No MicroSoft products installed.


png doesn't have anything to do with M$. png was developed as a patent free
replacement for gif after Honeywell asserted its patent rights over the
compression scheme used by Compuserve in the gif algorithym. But the patent
has run out, so gifs are royalty free now.

For pictures that are human made, like plain text and floor plans, gif or
png is a better format than jpg.
