The Free Software Foundation has some good stuff on copyrights and why they only use PNG on their website(s), and is on the philosophy page:

http://www.gnu.org/philosophy/philosophy.html

which in my opinion, is a great read. And as for the JPEG extension, wow! I knew it was too good to be true. Is there an open source alternative to JPEG? I am gonna do some research on that....

Thanks for the heads up, man
