You will need to install a user script manager extension to install this script.
This removes extraneous links (like user profiles below each thumbnail) from image galleries, so that users can select many images and open them all in tabs.
Opening multiple links in tabs requires an extension. Chrome has Open Selected Tabs. Firefox has Tab Mix Plus (under Menus -> Main Context Menu). Eza's Gallery Smoothener works without this feature, but requires it to be useful.
