The Theme Manager module allows you to import and export templates and their attached stylesheets, including any images they use, as "themes". This allows you to share your look and feel with other CMSMS users.
It is very easy to convert any kind of template to be used with CMS Made Simple. Many templates like this have already been converted and can be installed using the Theme Manager, the CMSMS community also shares themes for anyone to download and use at the CMSMS Themes site(external link).
