Plugin/Script to let user upload files

Hi,

Is there a plugin that lets registered user upload a file with description and maybe an image? For my project I am creating a game website where registered members can upload game files (Flash) along with its description and images. I don’t want to add user as authors and have them write a post or something.

Similar concept:

Please let me know if anyone knows of such plugin or script.

Thanks
