Corbis, the online image library, is set to relaunch an improved version of its Web site.

However, existing Corbis members will need to register once again after the site relaunches on November 15.

Corbis warns: "In order to accomplish this major upgrade, we need to reload our membership database. This means that your member information and any pictures or products you've stored in your Portfolio or Wish List will disappear."

The revamped Web site will offer free screensavers and money-saving offers when it relaunches on November 15.
