if you want to sell them as prints, you have to get a better image than that. they won't print that. and even if you didn't want it as a print, it doesn't present well like that. after uploading, if your not selling them as prints, you can only have a limited amount of keywords. after that you have to advertise so people know your here, and then you deal with them, and deal with the other stuff.
As Mike says you will need far better images than that, even if only selling originals and not prints. People will not purchase an image based on a photo like that I am afraid
