For example, Adobe’s Acrobat Reader lets users switch between pages in a PDF file by showing a series of thumbnails of the pages that can be seen.

When a website has a lot of pictures, like an online store with a picture catalog, thumbnail images are often used instead of larger images to make the page load faster. The user can then choose which pictures they want to see in full size.
