Abstract
A method for protecting digital images distributed over a network, including the steps of receiving a request from a client computer running a network browser, for an original layout page containing references to digital images therein, parsing the original layout page for the references to digital images, generating a modified layout page from the original layout page by replacing at least one of the references to digital images in the original layout page with references to substitute data, and sending the modified layout page to the client computer. A system is also described and claimed.
