// @name           Helgon.net anonymous gallery viewer
// @namespace      http://henrik.nyh.se
// @description    Adds an option to enlarge gallery images (in a new tab/window) at Helgon.net anonymously, i.e. without being stored as having looked at that image. This works by simply accessing the image directly instead of through a display page. The code has been made easily customizable.
