We have added an experimental search by image option on the homepage under 'Looking for a replacement part?'. This is using the brickognize tool. You should be able to use it with a phone, and easily upload an image from your camera. I'd be interested to hear any feedback on this.

I didn't pay much attention to the three numbers that were displayed, so it's possible these formed part of the design IDs or BOIDs and that's why they were returned as results.
Brickognize is awesome!
Works fine with parts, though showing several more results would be better in my opinion.
