You can do that. Install Quickpic (It's a gallery app, works much better than the stock gallery).
Open it, open the photo, hit the optionskey --> Edit --> Edit (the one with the quickpic logo) --> resize (the icon with the four arrows pointing to the center). Select a size and hit the checkmark at the top right. All done
