FYI: I tested out this cool feature in 220.127.116.11 for the first time. Cool stuff!
I did stumble across a bug though that seems to happen when I right click -> Auto Resize -> And then hold the right mouse down on the map and drag, instead of the left button.
That's kinda funny. I tended to accidentally hit the right click quite often, but all it did was move the upper left hand corner of the image to where the pointer was. But I don't think I held it down and dragged. I just don't remember. Still glad I found this though, getting 118 images to line up was a task (I actually missed a line in a row of images so I had to go back and do filler images to rest behind the main images). Doh! Still it looks great.
