Thumbnail

Thumbnails are reduced-size versions of pictures, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words. In the age of digital images, visual search engines and image-organizing programs normally use thumbnails, as do most modern operating systems or desktop environments, such as Microsoft Windows, Mac OS X, KDE (Linux) and GNOME (Linux).

Implementation

Thumbnails are ideally implemented on web pages as separate, smaller copies of the original image, in part because one purpose of a thumbnail image on a web page is to reduce bandwidth and download time. Some web designers produce thumbnails with HTML or client-side scripting that makes the user's browser shrink the picture, rather than use a smaller copy of the image. This results in no saved bandwidth, and the visual quality of browser resizing is usually less than ideal.

Displaying 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. However, this may mislead the viewer about what the image contains, so is more suited to artistic presentations than searching or catalogue browsing.

Thumbnail (cliff)

The Thumbnail is the sea cliff located in South Greenland in Cape Farewell region, ca. 50 km to the east from the town of Nanortalik, over the west side of Torssukátak Fjord (often known as Torssukátak Sound as it divides the main land from the Pamiagdluk Island). It belongs to the massif of Maujit Qaqarssuasia (also Qoqarssuasia), 1560 m a.s.l., being its eastern flank. The nearest peak dominating the neighbor ridges is Agdlerussakasit (1760 or 1706 m a.s.l.) and some of the reports on the climbs on the cliff also refer to this last name.

In 2000, 2003 and 2007 there were established 4 climbing routes on the east face, all starting from the sea. The hardest one is the earliest, British route, established in the steepest, right-hand part of the face in 2000 and graded as English E6, 6b or American 5.12c. The route finishes on the subsidiary top/outcrop (which was in 2000 called as Thumbnail itself) and has altitude approximated by altimeter as 1350 meters a.s.l. (originally 4490 ft, see references, AAJ 2001, pp. 64 and 70).
