Property thumbnail : Iv3ED; (Read/Write)
An abbreviated rendition of the full content.
A thumbnail requires significantly fewer resources than the full content, while still maintaining some distinctive similarity with the full content. A thumbnail is typically used with by-reference encapsulated data. It allows a user to select the appropriate content more efficiently before actually downloading through the reference.
Originally, the term thumbnail refers to an image in a lower resolution (or smaller size) than another image. However, the thumbnail concept can be metaphorically used for media types other than images. For example, a movie may be represented by a shorter clip; an audio-clip may be represented by another audio-clip that is shorter, has a lower sampling rate, or a lossy compression; or an abstract provided for a long document.
A thumbnail itself SHALL NOT contain a thumbnail.
