Avatar problem

[raphael.cruger]

Well no matter what i do i can't seem to upload an avatar for this forum account. I've made sure that the multiple files I've tried to upload repeatedly have been within the 120*120, 10kb limit (sometimes considerably lower just to check) but no luck. Here's the error I get
Warning: move_uploaded_file(./uploads/avatars/avatar_9684.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in /home/heroserver/domains/hero-server.net/public_html/forum/inc/functions_upload.php on line 266
