If you click a photo it brings you to the page for it. There is an 'Edit' button with an arrow to the right of it's name (Directly above the photo). Click the arrow and press 'Replace' then upload your new file. Make sure to check ignore warnings or else you'll get a bunch of messages about it being a dupe.
