Abstract
A method for serving an image from a server to a client, e.g., a computer having a browser or other graphics viewing engine. The user of the client first specifies a set of one or more bitmap characteristics for an image transfer, with at least one of the bitmap characteristics including a number of bits per pixel. Preferably, this specification is accomplished using an applet or other piece of code that is downloaded to the client from the server. Later, when the server receives a client request that includes data identifying a specified bitmap characteristic, a server processing routine (e.g., a servlet) generates a version of the image that conforms to the specified bitmap characteristic. This version is then delivered back to the client in response to the original request. In this way, the user of the client machine can control the particular characteristics of the image files that are delivered to his or her machine.
