Hi, I think what they are is 3D barcode images. These are images very much like the ones on the forum. They hold information.My phone has a barcode reader which, when you copy the image, stores the information. It saves you having to remember web addresses etc. Well I hope I'm right they look very similar. I know I haven't explained things very well but if you google 3D barcodes its all there. Hope this solves the mystery. Steve aka 5teveuk.
