I've moved jpegs to the Canon device on my iMac and then put it in the camera but I have a no images message on my camera view screen!  I really don't know what I'm doing with these machines if I don't have explicit instructions.  What is that yynnuu stuff in the pic above?  What is DCIM?  Do I need some additional software?  thanks, Haven

As a general rule, you can not put pictures from a computer back on the memory card to see on the camera.  So, what you are doing will not work.
