I occasionally use it that way for painted labels on parking-spaces at the airport. (I have yet to need them, but it seems a reasonable precaution given how even a small amount of floor/zone/row forgetfulness could leave me wandering the 10,000-spot complex.)

That said, I also find myself wishing I could mark those photos as "temporary", so that they get auto-deleted within a month or whatever.

Easy! At least on iphone, photos you delete are saved in the trash for 30 days. So - take the photo, and immediately delete it.

Assuming you're not parking for more than a month, your photo will be in the trash if you need it, and will be automatically deleted if you don't!
