Do you mean the tkImg library from <http://sourceforge.net/projects/tkimg/> ? If so, I have used it successfully by just adding a line root.tk.call('package', 'require', 'Img') (where root of course is my Tk() window). I have only used it for displaying .png images though, I don't know about this "snapshot" feature.
