A small version of a photo. Image browsers commonly display thumbnails of photos several or even dozens at a time. In Windows XP's My Pictures, you can view thumbnails of photos in both the Thumbnails and Filmstrip view modes.

"A thumbnail index can be thought of as a "contact sheet" in traditional photography terms. Most digital cameras allow you to view the images on the storage card in a thumbnail index as an option during playback. Most use a 3 x 3 grid of images, but this does vary between cameras (some even allow you to specify the number of images to be displayed in the index). Often you can still carry out basic functions such as deleting or protecting images while in thumbnail index mode.?TIFF: The Tagged-Image File Format (TIFF) is used to exchange files between applications and computer platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. This format of file uses the .tif extension. The TIFF format supports CMYK, RGB, and grayscale files with alpha channels, and Lab, Indexed Colour, and Bitmap files without alpha channels. TIFF also supports LZW compression."

"Protocol for exchanging information between application and devices such as scanners and digital cameras. TWAIN makes it possible for digital cameras to "talk" with one another on PC's."

Placing between or interpolating the area between pixels.
