I've been looking for a way to move a photo from LPJ's phone (where most of her photos are nowadays) directly to a frame. NO streaming, NO cloud, NO Flickr, NO accounts required. After some deep searching, I could only find one, though I would have preferred requiring the phone to be logged in on the same lan in order to transfer.

There's a 20% discount code buried down the page, so I'll give it a try.
