I have only posted photos taken with my Nikon Digtal. Now I've had some of my photos taken with my Canon AE1 SLR developed. I would like to post some of them. But the size they are automatically shows them to be 680x832 pixels. How do I change that? What do I do in my PHotoshop Image Sizing to change it? Can anyone help me?This is a photo I scanned on my scanner, should I maybe be scanning the negative instead?
