Allow users to upload photos & posts to a ‘profile’ page

I’m investigating whether this functionality is available with WordPress, and my searches have come up short. Can anybody point me in the right direction?

I’m looking to use WP to give my visitors the ability to signup to create an account that allows them to create their own “page” on my site, where they can upload photos and stories relating to those photos. The page is available to everyone to view, but only they can post to it. Anybody can post comments, and the user needs to be able to manage the comments.

Ideally, the user would never use the WP-admin to do this—the photo uploading, post submitting, and comment management would all occur on the page itself via AJAX controls only they would see because they are logged-in.

Is this functionality available via a plugin or has anybody experimented with something similar I can take a look at? Thanks!
