Thumbnails are reduced-size versions of pictures, used to make it easier to scan and recognize them, serving the same role for images as a normal text index does for words.

Overview

Some web designers produce thumbnails by simply reducing the dimensions of a large image using HTML coding, rather than using a smaller copy of the image. In practice the display size of an image in pixels should always correspond to its actual size, in part because one purpose of a thumbnail image on a web page is to reduce download time. The visual quality of browser resizing is also usually less than ideal. HTML, an initialism of HyperText Markup Language, is the predominant markup language for web pages. ...


Reducing a significant part of the picture instead of the full frame can allow the use of a smaller thumbnail while maintaining recognizability. For example, when thumbnailing a full-body portrait of a person, it may be better to show the face slightly reduced than an indistinct figure. This has the disadvantage that it misleads viewers about what the image contains, so it is less well suited for searching or a catalogue than for artistic presentations. For other uses, see Portrait (disambiguation). ...
