GIF policy

Since a patent on the LZW compression algorithm used in GIF images is held by Unisys, and OpenSource software normally used under Linux is typically not licensed, all GIF images here are being replaced by PNG or JPEG.

This may result in images being inaccessible to older browsers. Apologies for the inconvenience. For more information and links to Unisys, PNG software etc. please see Burn All GIFs
