A thumbnail picture is a reduced-size picture that points at a larger original picture.
Pictures can be very large files and can take a long time to download over the network.
Thumbnails provide a quick preview of the contents of a picture. If the picture is of interest, you can still download and view the full-sized version of the picture. Ingredients GraphicConverter Procedure Start up the GraphicConverter program and open your picture file in GraphicConverter. GraphicConverter shows you the size of the picture in the info window.
