Wallpaper Pictures 04

Picture search engines aim to do the impossible: to read pictures. The problem is that search engines in general are only able to read texts. That's why even big photo sites have to make use of clear descriptions of each photo, because without the text they will not be able to index the pictures and the photos will remain unknown for the web surfer.

You need to know these limitations of search engines if you search for pictures but also when you use pictures online yourself.

The special picture search engines are developed to make the most out of the impossible conditions when searching the web for photos and other pictures. Google and Yahoo and other big search engines (SE) have had to develop special search engines to cope with picture search.
