Google has launched a new way to search - by image. Whereas before you could search via text for an image, now you can use the image itself. With some surprising results as I found when using a profile photo I have of myself.
Google didn't find where I'd used the photo. Other photos I tried would show me places where the photo had been posted or used. For this photo it did make some suggestions of visually similar images - I think this is based on colours. Some of those suggestions were surprising...
Especially the one on the bottom right corner. I look like a bare bottom? I shall run away to bare bottom land!*
