i've setup magento CE 220.127.116.11 on a webserver nginx on 12.04 ubuntu cloud server. i've change configuration in order to use cdn for media, skin and js but i have some issues. for instance i can't upload new images for the product. no error shown, but the link of image is broken. i've just started using magento so maybe i'm doing something wrong but can't figure out what.
