I remember this was driven by a large company claiming copyright on the GIF standard. The base reference here is http://www.w3.org/Graphics/PNG/ and more information is at http://www.libpng.org/pub/png/slashpng-1999.html This latter article (dated 2000) does contain this statement "The patent issue is largely history, except to shareware and freeware authors, for whom it's still quite real--Unisys lawyers continue their apparent crusade to kill all low-cost GIF-supporting software." So it may be history now but use of PNG would avoid any possible problems. The article also states that both Netscape & IE have supported PNG since version 4 (in both cases) so it should not cause any problems - but that is what Beta testing is about.
