re: oops
Yes, it was the standard "macaroni" image that everybody saw. I did an annotation of the image, using small rectangles, where several other "macaroni" type feature were identified. No easy to spot that features at first but after a while you can see them everywhere. They look as sequences of cemented grains. So there is no "url "at which I can point to...and uploading the image could be the only way to go...
