As of 19 May 2010, TinEye claims to have indexed 1,475,683,239 images for comparisons. However, this is a very small proportion of the total number of images available on the World Wide Web.http://en.wikipedia.org/wiki/TinEye (footnotes redacted) The footnote to that second statement notes that Flickr alone, for example, hosted over 4 billion images as of October, 2009 (that number has only gone up, since then).
