Photo collect download plugin (I'm finding this difficult!!)

Hey guys,

We’re running a community carols event at the end of the year. One of the features will be a photo booth and I’m hoping to set up a collection point on our website.

We want to give people a code which they’ll enter on the website, then it’ll pull up their photo to download and/or be emailed to them. It shouldn’t be a classic “gallery” since we don’t want everyone’s photos publicly accessible; only their own individual photo, which they’ll collect using the code.

I’ve looked at a number of plugins but haven’t read any descriptions that sound suitable. Does anyone have an idea of what plugin might work?

Thanks very much,
Dan.
