Thumbs up for changing that picture in the Wiki. Please not post this Pflasterstein_1 image anywhere else, it is just no good in telling both mappers and consumers anything of helping them decide.
May I repeat: Pictures should be at another angle than straight on and show something from which casual observers can learn dimensions at a single glance? I’d say this also applies here: Two salt’n’pepper images, one salt’n’pepper on Mars, one maybe some salt under the microscope? Please excuse perhaps over the top direct language.
