Okay, stupid question I'm sure but, I was asked for an image that was 3mb jpeg size (at least) and when I look at my sizes I see thumbnail compression sz of 6 jpeg and disk sz of 2.8 mb and memory of 19.22
The size of the picture is: 3456 x 1944 Pixels
Which is the correct mb jpeg size?
Also, am I missing where the DPI is?
