???Are you asking why the pictures are larger on your computer screen than on your smart phone?
Just kidding, I downloaded one of the pics and it is at 3000 * 4000 pixels. That is pretty big. So if you are claiming that some people see them unmagnified, then that is not true, because they are actually significantly reduced to fit on your screen or the display window allocated by the forum software.
I'm going to ask my buddy, keyboard guy, computer wizzard, to explain to me what's up.
