I've been noticing weird things with the revision menu in pholio. I'll submit a task if/when an issue is found. For now enjoy these test images.

Seems to be just confusion on my part. I was trying to replace an image so I removed the previous one and then added the new one with the same title and this showed up in the revision window as two different images because I didn't know you could replace images by dragging and dropping on the previous one.
