STEP ASIDE HALLMARK. Corbis has moved into the greeting card business by teaming together with AltaVista, the popular Internet search engine. Customers using the search engine can pick out an image from the 500,000 "Corbis Picture Experience" collection and employ it in a greeting card that can be sent to anyone with an Email address. Check out the "services" section on AltaVista and click on the free "Create a Card" section that will take you to the Corbis site.
