Hi guys, I just learned that the whole website of gnu.org doesn't use GIF images. I just read through the reason and was bombed :-)
Crux of the Reason: Unisys and IBM have patented the LZW compression algorithm which is used in generated GIF images. Read the full article.
Also, the page links to a library called libungif, which uncompresses GIF images written using the LZW algorithm and writes them in uncompressed format. The philosophy section of GNU.org is very interesting. Please go through it.
hmm...
