template
A template is a design that defines a page's basic structure, from its navigation and basic layout to colors and font styles. Most site building and blog tools include professionally designed templates you can choose for your pages to save time and give your site a unified look.
thumbnail
A thumbnail is a small version of a large image. The larger an image (in file size and actual pixel dimensions), the longer it will take to download into a web browser. Because small images take much less time to load (in other words, to be rendered), thumbnails are often used on a web page or in an application to allow the viewer to quickly scan a series of images. Generally a viewer can click on or move his mouse over the thumbnail to load and view the full-size or larger image.
