anonymous image upload

I have a blog running (funnily enough) and im looking to add a gallery page. I want to have an anonymous upload feature on that page that allows anonymous users to upload their own image. The image then sits in the dashboard awaiting my moderation (approval) and once approved gets displayed on the ‘gallery page’ that i can then style up pretty and include a lightbox etc.

Does anyone know of a plugin that handles anonymous user image uploads, with moderation?

Any help or nudges in the right direction would be greatly appreciated.
