If you have large images on your website that you want to preview, you will need to create thumbnails of those images. These small preview images allow users to quickly find the images they want to view without waiting on full-sized versions to load each and every time. Most thumbnails are made of .JPG images, a common format among images on the Internet. Creating .JPG thumbnails is a straightforward task that should only take minutes to complete with any image-editing software.
