Nothing is what you've got.
As you scroll through the photos, all you see is the blurry green and brown of the branches blocking your lens. You didn't manage to get a single good photo of anything. Not the houses, not the people, not even the lilacs.
There's one picture where you can sort of tell that it's a woman in a white dress, but it's fuzzy enough that it might as well be a picture of Bigfoot. Which doesn't help to resolve the question of whether she's a ghost or not. You suspect that maybe she isn't, but who knows? You've dealt with magic before, but never ghosts. Maybe the rules of ghosts don't work the way you thought they did.
If you're going to get evidence about this place beyond what you've seen and heard, you're going to have to do it another way.
