For MediaWiki:Common.js you need to replace two parts: mwCustomEditButtons.push( {    "imageFile": " https://images.wikia.nocookie.net/marveldatabase/images/0/02/Eyetem_Button.png",     "speedTip": "Insert item template",     "tagOpen": "",     "sampleText": ""} );
 * For item

mwCustomEditButtons.push( {    "imageFile": "https://images.wikia.nocookie.net/marveldatabase/images/f/f2/Location_Button.png",     "speedTip": "Insert location template",     "tagOpen": "",     "sampleText": ""} );
 * For location
