Thumbnail

A thumbnail is a reduced-size version of a digital image or video. Thumbnails are used to make it easier and faster to look at or manage a larger set of images or videos. Instead of loading the full-resolution file, which can consume considerable bandwidth and processing power, users can view multiple thumbnails at once to quickly identify the content they are looking for.

Thumbnails serve as visual placeholders and links to the full-sized versions of the original content. Clicking on a thumbnail typically loads the larger, higher-resolution image or video.

The size and resolution of a thumbnail are intentionally smaller than the original. The specific dimensions can vary depending on the application or context in which the thumbnail is used. Common uses for thumbnails include image galleries, e-commerce websites, video streaming platforms, and operating system file browsers.

The creation of thumbnails is often automated, using image processing algorithms to resize and sometimes compress the original image. Efficient thumbnail generation is crucial for maintaining performance and responsiveness in applications that handle large amounts of visual content.
