1. A method of deduplicating images in a single document, the method comprising: identifying, by a computer processor, a plurality of similar images in the single document, wherein the identifying includes: populating a table with weighting factors for each of a plurality of parameters associated with a plurality of images, the parameters including image title and image tags, such that the table includes weighting factors for the image title and the image tags for each of a plurality of images; generating weighted graphs based on the weighting factors, wherein the plurality of images are depicted as nodes in the weighted graph and a cumulative edge weight between nodes is generated by the cumulative application of the weighting factors for each of the plurality of parameters, wherein at least one of the cumulative edge weights between nodes is greater than zero; and using the cumulative edge weight between nodes to determine the plurality of similar images; presenting, by the computer processor, the plurality of similar images with the respective cumulative edge weights to a user via a graphical user interface; designating, by the computer processor, the one of the plurality of similar images as a master copy based on a received user selection of the one of the plurality of similar images as the master copy; and replacing, by the computer processor, each remaining one of the plurality of similar images, other than the master copy, with one of (i) a duplicate copy of the master copy and (ii) a soft link pointing to the master copy, wherein the single document is an electronic document of a word processor application.
