A: Please do not edit your pictures. If people like the pictures you made, they would like to have the original photo. The website will scale them down to smaller thumbnails and screen sized photos, but if you click on a screen size photo, the original photo will be presented. If available... On the other hand, handling 8 million pixel pictures at 3 MB a piece is quite a hassle. If you take pictures, a pixel width between 1600 to 3000 pixels will do fine when used for printing.
