1. A method of tagging photos utilizing a computer-implemented photo display system, comprising: receiving by the photo display system a plurality of images comprising a plurality of individuals; detecting facial regions in the plurality of the images received at the photo display system; grouping the plurality of digital images into one or more clusters based on similarities between the facial regions; receiving input from a user at the photo display system, wherein the input comprises a tagging data; assigning the tagging data to the one or more clusters to generate tagged clusters; calculating correlation factors by comparing untagged clusters with tagged clusters; assigning suggested tagging data to the untagged clusters based on the correlation factors; and selectively displaying the untagged clusters with the suggested tagging data.
