Thumbnails were shown to users visiting the Picsearch image search engine, and popularity measurements were derived based on the ratio between how many times each images has been viewed and clicked (only for images that have been viewed more than 50 times). The 100 most popular images in each category are marked as popular. The emodb database contains 70 image folders, corresponding to different categories/keywords. Each folder contains thumbnail images in jpeg format, together with a txt file of the same name as the folder.
