Not seeing my Secondary aerial images

I have gone through the process of adding my secondary aerial images. I can only see them when I turn off photo-geometry. I have a polygon for the whole area and I selected exclude all, but I am still not able to see it. This used to work fine but now it doesn’t. Any ideas. Thanks

What’s the LOD parameters you used?

It has been a while since I made my Bing tiles, but I think it was 20. Why, what difference does it make?
