Cropping Guide in Output - print, websites, Facebook, email, client disk, etc Posted July 13 Hi, D, I have a friend who thinks a 12 mb photo isn't big enough to print on a wall. He thinks it should be LARGE--20mb jpg. Where do I find where you said anything 6mb or larger can be printed on an 18-wheeler? I have the cropping guide. I just want to take a screen shot of your explanation of cropping.
