Allposters sell posters from movies such as Twilight and very popular cult films like Pulp Fiction, but also they sell fantasy art posters which are very good to buy, also though they have an affiliate program that you can sign up for below with the banner, so that you yourself could earn some extra money.
The posters are good quality and mainly because I own a few fantasy art posters from there I know that they are of excellent quality and would highly recommend them to anyone.

Also if you are looking for a place to store your drawings, photos or other design images, then why not try Shareapic and plus you can also earn from the image views that you generate per image, does require a large amount of traffic to earn, but hey there are some great artists out there and storing your images elsewhere for free is a good option.
