here i am... :-) yes, i uploaded a lot of posters at zazzle.com. the quality is quite good (as far as i got feedback from wojteg, who has one). and of course it depend on what you upload. if you render your images with high resolution you will get good posters. the payment works by check every month. but i sent mine back because i have to pay too much expenses to the bank here in switzerland. and i did not buy yet my posters at zazzle, because of the shipping coasts.
