Well, I figured it out. It's still an issue for you to fix, but not what I thought. Here's the deal...
BEFORE you upload / place the FIRST photo for each zone on the iPhone, there is a photo box square that has white to the left and white to the right, with very faint grey icons (take photo button on left and photo roll button on right)
They are faint, but easy to see because the borders are white.
AFTER you upload a photo to a zone, the photo takes up the the whole area (landscape, not square) and those icons are nearly impossible to see depending on your images. I clicked in just the right spot and I actually am able to change photos... I just had no way of knowing that without a bit of luck. Once a photo is placed, those icons need to be bright orange or something, or maybe have an outline of some kind. I found a handful of threads in the forum all talking about this very issue, and I guarantee if you change those icons to be obnoxious somehow, this issue goes away.
