User data files for electronic images and/or other types of information are stored in a server coupled to a display such as a television set and having interfaces with one or more communication networks. Priorities of individual user data files are modified based on prior activity regarding those files. File activities affecting priority can include enlarging an image, editing an image and copying an image to another folder. When the user views an array of thumbnail images, thumbnail images are only displayed for user data files meeting a priority threshold. The user can adjust the priority threshold so as to increase or decrease the number of thumbnail images shown. The invention is applicable to numerous types of data, files and file formats, as well as to numerous manners of providing information regarding files.
