Apparently some version of AOL Browser does not handle PNG graphics at all, and instead prompts to download them. Either the same browser, or another, invokes RealDownload on the PNG graphics each time they're displayed. I removed the PNG graphics from FreeRepublic until I can find a more acceptable format. GIF graphics are encumbered by patents, the patent holder requires a royalty payment for each graphic generated, so that isn't a go. Will probably end up with JPG graphics. Sheesh.
