Search engines - Surfing the web without search engines? Hard to imagine, I think.
They do (well most of them) a pretty impressing job. Whatever we're looking for, we type it in and within a few seconds we get 84,000,000 search results. Whether it be sites, images, places or documents - search engines on the web became so important to us we even invented new verbs. But have you ever tried to 'google' an image?
I know, it sounds weird, but so far, search engines work with the word tags you provide and they look for matches on the web.
Well how about TinEye? TinEye is a reverse image search engine that finds out where an image came from, how it is being used, if modified versions of the image exist, or if there is a higher resolution version.
Pretty cool uuh? I like it. Check it out.
