Format and method for representing a dynamic digital image

1. A computer implemented image rendering method for rendering a digital image using computer data organized in an image format where the image format includes image data and computer executable instructions, the method comprising the steps of:

receiving the digital image organized in the image format wherein the digital image includes original image data and computer executable instructions, and wherein the image format further includes program variable data that is accessed by the computer executable instructions during execution;

establishing a virtual execution environment to execute the computer executable instructions wherein the virtual execution environment provides an application program interface used by the computer executable instructions to receive information and request services and wherein the virtual execution environment provides the computer executable instructions access to the image data, and wherein establishing the virtual execution environment further includes providing the computer executable instructions access to the program variable data and wherein the information received by the computer executable instructions using the application program interface includes local environment information including the source of the digital image and information that uniquely identifies the computer executing the method;

executing the computer executable instructions within the virtual execution environment wherein the computer executable instructions, when executed, use the application program interface to receive information and request services from the virtual execution environment and wherein the computer executable instructions use the received information to generate new image data; and

receiving the new image data as output from the computer executable instructions.

2. The method of claim 1 , wherein the computer executable instructions are generated by a compiler program from instructions written in a computer programming language.

3. The method of claim 1 , wherein the computer executable instructions are written in an interpreted computer programming language.

4. The method of claim 1 , wherein the services provided by the application program interface includes a retrieve web data service that includes receiving a Uniform Resource Locator (URL) from the computer executable instructions that identifies a web page on a remote computer, performing a page request on a network using the URL, receiving data in response to the page request and returning the data to the computer executable instructions.

5. The method of claim 4 , wherein the computer executable instructions, when executing within the virtual execution environment, communicates with a remote computer wherein the communications include sending information to the remote computer by encoding the information in the page request used by the retrieve web page service to request the web page and receiving information from the remote computer by receiving the response data from the page request.

6. The method of claim 5 , wherein the information retrieved from the remote computer includes information used by the computer executable instructions to decode the image data stored in the digital image.

7. The method of claim 5 , wherein the information retrieved from the remote computer includes supplemental image data used by the computer executable instructions to modify the image data stored in the digital image to generate the new image data.

8. The method of claim 5 , wherein the information retrieved from the remote computer includes second image data and the computer executable instructions use the second image data instead of the image data that is already stored in the digital image to generate the new image data.

9. The method of claim 5 , wherein the information retrieved from the remote computer includes information used by the computer executable instructions to generate the new image data.

10. The method of claim 5 , wherein the information sent to the remote computer includes the information that uniquely identifies the computer executing the method.
