Guests create albums and submit photos

Hey guys, I’m currently developing an event website and I want guests of the event to be able to visit the site afterwards and upload pictures they’ve taken, I know there are a few options available but I have some very specific requirements and would like to know if they’re possible to achieve.

So after the event visitors will come to the site, and will see a link to a submit page. On this page I want an upload form (much like the usual drag and drop upload area within the WP dashboard) with a field to create an album name and name of uploader (possibly before the upload form appears?) so that each album is separate.

Obviously this leaves the site open to a heck of a lot of spam, so I want to have each album submitted like a comment; to be approved by the site admin. I’d rather not have guests have to create an account on the site if possible, because it will save time and hassle just to approve things as and when they come in.

If you have any suggestions for plugins or code options then I would really appreciate it

Cheers
Kris
