Google Image PageRank for images named VisualRank

The International World Wide Web Conference in Beijing saw Google Research Engineers presenting a paper on PageRank for Google Images to improve search results for images available through Google Images.

Googles new system promises improved image results through the use or VisualRank, the benefits being a reduction of duplicate image content, image spam or inappropriate images.

Better start optimising your site images for this, I’ve heard many do already, though I’m unsure as to how much genuine traffic actually comes from Google Images, something to find out.
