How do I install the powerpoint templates from templateswise.com?

Each powerpoint template I downloaded comes with a folder with a number on it. Inside the folder is a bunch of jpg images and 1 .pot. What do I do with them and where do I put each file/folder?|||Not sure. I use the templates directly from the Microsoft Office template site. I don't like to use lesser known sites for stuff like that because they tend to include viruses or spyware.
