What are image thumbnails?
A thumbnail is a small picture of a larger picture. Its purpose is usually to make it easier and faster to look at or manage a group of larger pictures. File browsers, image viewers, and web pages all use thumbnails. People think that the word “thumbnail” came from the fact that a thumbnail is about the same size as a human thumbnail. Thumbnails are usually much smaller than the original image, but they still have enough detail to show what the image is.
There are several reasons to use thumbnails. First, they can make it faster to look through large collections of images. File browsers can show more images on a single screen by showing thumbnails instead of full-size images. This makes it easier to find the image you want. Second, thumbnails can help you put images in order. By putting thumbnails in groups, users can see at a glance which images go together. This can help you keep track of your photos, screenshots, and other images.
