This is in reply to Bad_CRC's message on Posted 12-22-2000 09:11 AM. The URL's on that message can be viewed by copying and pasting the URL into your browser bar. Xoom, it seems, wants you to only link to images from your xoom.com page, so if the referring URL isn't a xoom page, it disables the link. But, since not all browsers provide the referring URL, they have to allow requests without the referring URL - and you can spoof this by just copying it into the browser.
You should all check them out, some are pretty good. It's on p.20.
