It's a good explanation of how the template system works.

dolphin_jay, if you want to replace the stat images in your new template, name the picture the same name and the template will assume the new picture you have included.

The template system will cascade style sheets but images, html files and php files. It's all there. It will carry through to the modules.

You will need to adjust some files in the forum and the php file see more that defines the template.
