The image gallery seems to utilize Page.ss for the style of the page. My client wants a different template applied to the gallery page (not page.ss) and Page.ss applied to the album pages. I would imagine this is possible, but I'm not sure where to begin. Any direction would be appreciated.
Just create your own ImageGalleryPage.ss in your theme_dir/templates/Layout directory. If you want the "wrapper" of the site, that is, everything around the $Layout part to change for the ImageGalleryPage class, then create a ImageGalleryPage.ss in your_theme_dir/templates, as well (at the same level as Page.ss)
