The Borealis image server is intended to address the need for creating a central place to store large numbers of images. The system itself is composed of widely available resources and could be easily reproduced at other sites at very little expense. A Borealis server can be queried from any Web page or browser and delivers an image which has been watermarked. This watermarking is intended to assert ownership of the image in an obvious but unobtrusive fashion. The server is managed using a database which ensures that picture IDs are unique throughout the server. A variety of output styles are supported, including the image in its full size, a reduced version of an image, and a dynamically generated HTML information page. Images may also be returned in a variety of graphic formats. Future enhancements should include Web page-based administration tools, support for authenticated users to view non-watermarked images, and more advanced file management. Through these and other enhancements, the Borealis Project should fill a critical gap in the effort to make images available on the Web.
