Airfolio theme Problem.

Hi! I don’t know if anyone can help. But I installed wordpress and the theme of ThemeForest, from the Ivystudio, the Airfolio, and everything works, and taking the fact that you can not insert images. Not in nivoslider the homepage or any other. I went to the uploads folder and they are there. In the backoffice appear in wordpress, but then nothing on the site. Does anyone have any idea what might be. Have tried to contact them, but so far no answer. The site is: http://www.wonderdesign.net.

thank you very much
