Hi, I notice you've been uploading some chemical diagrams as JPEG files; unfortunately this leads to very poor image quality because of JPEG's lossy compression. If you're creating the JPEG files yourself, you might consider resaving the original files in PNG format instead, which should give a clean image. See also the Image use policy for other recommendations. --Brion 05:45 Oct 28, 2002 (UTC)
