Need to create access for user to upload

is there a way for a user to have access to upload files to a server without using cuteFTP. (something along the lines of the way you upload avitars and such in a forum.

here is where i need it for –Xtreme speedway in the paint schemes section – i want people to be able to upload cars without having to use ftp access.

is this possible? let me know if i need to provide more info. as i am typing this i realize it made more sense in my head.
