In an example embodiment, a request that includes a first image is received. A second image and a description are accessed from an item listing. An item identifier that corresponds to the second image is parsed from the description. A first edge in the first image and a second edge in a second image are detected. A match between the first image and the second image is determined based on the detection. The first image is associated with the item identifier. Item information corresponding to the item identifier is accessed from web pages. The item information is then transmitted.
