1. A system, comprising: an image filtering component configured to detect and remove unwanted images from an indexer download work list as part of indexing search content, the unwanted images detected based on a detection algorithm that predicts that an image is unwanted based on image feature information that comprises a probability a given unwanted image is of a file extension type; and a microprocessor configured to execute computer-executable instructions associated with the image filtering component.
