Thumbnail

Thumbnails are small, scaled-down representations of larger images, videos, or content items. They serve as visual previews that provide users with a glimpse of the full content without requiring them to access the complete version. Thumbnails are commonly used in contexts such as image galleries, video playlists, search results, and content previews.

The primary purpose of thumbnails is to enable users to quickly assess the content's relevance, helping them decide whether they want to explore further. They aid in reducing cognitive load by allowing users to preview multiple items at once. Clicking on a thumbnail often leads to the full content, enabling a seamless transition from preview to detailed view.
