Abstract

In some example embodiments, a system and method are illustrated to link item images to item listings. The system and method include receiving an item listing and an image for the item listing from a user device. The system and method include assigning an image identifier to the image received from the user device. The image identifier may be identical or substantially identical for the same or similar images and unique for different images. The system and method include comparing the image identifier with one or more existing image identifiers. The system and method further include linking the received item listing to an image according to a result of the comparing. In some example embodiments, the system and method include receiving the image identifier from the user device and determining whether to receive the image for the item listing from the user device according to the result of the comparing.

counting the number of item listings; and

discarding the existing image if the number of item listings is zero.

6. A computer-implemented method, comprising:

receiving an image identifier associated with an image for an item listing from a user device, the image identifier being substantially identical for similar images and unique for different images;

comparing the image identifier received from the user device with one or more image identifiers for existing images for existing item listings; and

determining whether to receive the image for the item listing from the user device according to a result of the comparing.

7. The computer-implemented method of claim 6, further comprising sending the result of the comparing to the user device, the result indicating whether the image associated with the image identifier matches any of the existing images.

8. The computer-implemented method of claim 6, wherein the determining whether to receive the image from the user device further comprises:

if the result indicates that the image does not match any of the existing images, then receiving the item listing and the image for the item listing from the user device; and

if the result indicates that the image matches an existing image, then receiving the item listing from the user device and linking the received item listing with the existing image.

9. The computer-implemented method of claim 6, further comprising:

receiving an override notification from the user device, the override notification indicating that the image is to be transferred regardless of the result of the comparing; and

receiving the image from the user device.

10. A computer-implemented method, comprising:

providing an item listing and an image for the item listing to be transferred to a host device;

assigning an image identifier to the image, the image identifier being substantially identical for similar images and unique for different images;

transferring the image identifier to the host device to be compared with one or more image identifiers for existing images for existing item listings stored in the host device;

receiving a result of the comparing from the host device; and

uploading the image to the host device according to the result of the comparing.

11. The computer-implemented method of claim 10, wherein the uploading of the image to the host device further comprises:

if the result indicates that the image does not match any of the existing images, then uploading the image and the item listing to the host device; and

if the result indicates that the image matches an existing image, then uploading the item listing to the host device and linking it to the existing image.

12. The computer-implemented method of claim 11, further comprising:

sending an override notification to the host device, the override notification indicating that the image is to be transferred regardless of the result of the comparing; and

transferring the image to the host device.

13. The computer-implemented method of claim 10, wherein the image identifier is generated by an image identifier generating engine distributed from the host device.

14. The computer-implemented method of claim 10, wherein the host device is another user device.

15. A computer system, comprising:

a receiving engine to receive an item listing and a tentative image for the item listing from a user device;

an assigning engine to assign an image identifier to the tentative image, the image identifier being substantially identical for similar images and unique for different images;

a comparing engine to compare the image identifier with one or more image identifiers for existing images for existing item listings; and

a linking engine to link the received item listing to the tentative image according to a result of the comparing.

16. The computer system of claim 15, wherein the linking engine is further configured to:

if the result indicates that the tentative image does not match any of the existing images, then link the received item listing to the received tentative image; and

if the result indicates that the tentative image matches an existing image, then discard the tentative image and link the received item listing to the existing image.

17. The computer system of claim 15, wherein the assigning engine is further configured to assign the image identifier as a function of a hash algorithm.

18. The computer system of claim 15, wherein the receiving engine is further configured to set a listing period for the received item listing.

19. The computer system of claim 18, wherein the linking engine is further configured to discard an existing image as a function of the number of item listings linked to the existing image, the discarding comprising:
