Well, It's not loopable, the first and last should also match so that actually could LOOP through all the images.. Also, you can see for yourself that the two middle images have problems with alignment of the original images in them.
i guess maybe cause its a panoramic view and goes on an angle. And yeah i guess the loopable thing is from 1-4 and doesnt keep going. I just wanted to see if this would work to a point i guess there is a lot more to work on..
