How to create a multi-user gallery?

[bouncer]

Hi all,

So I'm working on creating a multi user photo sharing site similiar to these two sites: behance.net and dribbble.com

My site is at www.slimfolio.com

I already have a user registration system. I just have no idea where to start on creating the upload photo and to display it. Like the entire system for sharing a photo.

Any ideas/help please?

Thanks.
