No, it doesn't have to be your backyard, just make sure it's outdoors. And I'd prefer it'd be your own property, but I wouldn't know the difference, so it doesn't really matter.

Yes, it can be a photograph you already have, but if you're submitting multiple entries, try and keep the majority of them recent.
