Daniel!
I think we found where the problem is! It looks like when the post has a gallery using photos in other galleries and the post format is set to Gallery, the images do not appear. This seems like a bug.
Since this is a premium theme, and we now know the specific issue (and it appears to be theme-related), I'd recommend posting the specific issue here:
http://premium-themes.forums.wordpress.com/forum/photography
You'll be able to get help directly from the developers.
If you'd like to start that thread over there and then come here and post the link to the thread, it would be great.
