Gathering the needed files

Every theme you create or edit will not be complete unless you use good pictures. You may need to search of some icons, in case you do not want to make them yourself, or in case you can create your own pictures this will further brand your forum. Gather as many images as you can, for one subject and choose the best, you may fit them somewhere in your forum, and they can add a nice touch, for example, the navigation bar has several icons.
