If you have ever in need of create a thumbnail image of a site, or just get an image of a site, there are a lot of services out there that offer that capability online. The best one I have found so far for casual usage is:
By providing it with a URL, Thumbalizr will return you a screenshot of the site in a variety of formats. You can even specify a custom size. Their prices seem to be reasonable for a heavier type of usage but if your goal us just to capture a quick screenshot and you don’t want to worry about editing it, Thumbalizr is the way to go.
