OK, I've edited a lot of images over the years (I use Paint Shop Pro) but never really thought too much about this and I'm obviously missing something. I'm working on some photos to be 300 dpi at 4x6 and 5x7 inches. But even though I've set them to no compression (1) when they're saved, the jpgs are coming out at much less that what I would think they should. For example a 4x6 image at 300 dpi should be 2.16 MB, right? (1200 x 1800 px). My jpgs are coming out at under 1 MB. Maybe another setting somewhere?

Thanks, Diana
