On the image viewer, when the first ref image loads you can see it as it's loading. Once we go to the next image, it doesn't show until it's fully loaded. If you have a slow connection it kind of seems like it's doing nothing. There's a loading message by the timer, but it's easy to miss.
1) See if we can somehow show the image as it loads. We might be at the mercy of the browser behavior, but worth a little experimentation.
2) If that's not an option, make the loading indicator more obvious. Maybe put it on top of the image and show an animation or something.
