ThumbnailA thumbnail is a miniature rendering of a graphical image. Thumbnails are frequently inserted in HTML documents, often with links to a larger image.
A thumbnail is often used as a link to the full-sized version to save space on an HTML page or to avoid extended downloading time. Including image file size information allows users to estimate how long the files will actually take to load.
Thumbnails can be created by a variety of viewing applications such as LView. Thumbnails may be of any graphic format.
