Abstract

Methods, systems, and products for distributing images in a data processing system, including receiving a request for a dynamic server page having a multiplicity of associated images, each image having a storage location identified in the dynamic server page by an image resource locator; inserting in the dynamic server page an image group identifier for the images; and inserting in the dynamic server page client data names for the images. Typical embodiments also include receiving from the client a request for a group of images, wherein the request comprises the image group identifier; retrieving from storage the images identified by the image group identifier; and sending the retrieved images to the client.

Claims

1. A method for distributing images in a data processing system, the method comprising:

receiving a request for a dynamic server page having a multiplicity of associated images, each image having a storage location identified in the dynamic server page by an image resource locator;

inserting in the dynamic server page an image group identifier for the images; and

inserting in the dynamic server page client data names for the images.

2. The method of claim 1 further comprising:

receiving from the client a request for a group of images, wherein the request comprises the image group identifier;

retrieving from storage the images identified by the image group identifier; and

sending the retrieved images to the client.

3. The method of claim 1 wherein inserting an image group identifier comprises inserting a markup element that includes the image group identifier, wherein the markup element represents an instruction to retrieve, during a single communication connection to the server, all images identified by the image group identifier.

4. The method of claim 1 wherein inserting client data names further comprises inserting in the dynamic server page content as rendered markup elements representing instructions to display the images at client display locations.

5. The method of claim 1 further comprising storing the images as a group on a server, including storing with the images an image group identifier, a dynamic server page name, and client data names for the images.

6. The method of claim 1 wherein inserting a client data name for each image further comprises replacing the image resource locators with client data names

7. The method of claim 6 wherein the image resource locators are set forth in HTML <

elements in the dynamic server page and replacing the image resource locators with client data names includes replacing the <

img>

elements with markup elements comprising the client data names.

8. A system for distributing images in a data processing system, the system comprising:

means for receiving a request for a dynamic server page having a multiplicity of associated images, each image having a storage location identified in the dynamic server page by an image resource locator;

means for inserting in the dynamic server page an image group identifier for the images; and

means for inserting in the dynamic server page client data names for the images.

9. The system of claim 8 further comprising:

means for receiving from the client a request for a group of images, wherein the request comprises the image group identifier;

means for retrieving from storage the images identified by the image group identifier; and

means for sending the retrieved images to the client.

10. The system of claim 8 wherein means for inserting an image group identifier comprises means for inserting a markup element that includes the image group identifier, wherein the markup element represents an instruction to retrieve, during a single communication connection to the server, all images identified by the image group identifier.

11. The system of claim 8 wherein means for inserting client data names further comprises means for inserting in the dynamic server page content as rendered markup elements representing instructions to display the images at client display locations.

12. The system of claim 8 further comprising means for storing the images as a group on a server, including means for storing with the images an image group identifier, a dynamic server page name, and client data names for the images.

13. The system of claim 8 wherein means for inserting a client data name for each image further comprises means for replacing the image resource locators with client data names.

14. The system of claim 13 wherein the image resource locators are set forth in HTML <

img>

elements in the dynamic server page and means for replacing the image resource locators with client data names includes means for replacing the <

img>

elements with markup elements comprising the client data names.

15. A computer program product for distributing images in a data processing system, the computer program product comprising:

a recording medium;

means, recorded on the recording medium, for receiving a request for a dynamic server page having a multiplicity of associated images, each image having a storage location identified in the dynamic server page by an image resource locator;

means, recorded on the recording medium, for inserting in the dynamic server page an image group identifier for the images; and

means, recorded on the recording medium, for inserting in the dynamic server page client data names for the images.

16. The computer program product of claim 15 further comprising:

means, recorded on the recording medium, for receiving from the client a request for a group of images, wherein the request comprises the image group identifier;

means, recorded on the recording medium, for retrieving from storage the images identified by the image group identifier; and

means, recorded on the recording medium, for sending the retrieved images to the client.

17. The computer program product of claim 15 wherein means for inserting an image group identifier comprises means, recorded on the recording medium, for inserting a markup element that includes the image group identifier, wherein the markup element represents an instruction to retrieve, during a single communication connection to the server, all images identified by the image group identifier.

18. The computer program product of claim 15 wherein means for inserting client data names further comprises means, recorded on the recording medium, for inserting in the dynamic server page content as rendered markup elements representing instructions to display the images at client display locations.

19. The computer program product of claim 15 further comprising means, recorded on the recording medium, for storing the images as a group on a server, including means, recorded on the recording medium, for storing with the images an image group identifier, a dynamic server page name, and client data names for the images.

20. The computer program product of claim 15 wherein means for inserting a client data name for each image further comprises means, recorded on the recording medium, for replacing the image resource locators with client data names.
