i think this is being caused by the file name:
beadbag-(2)_1.jpg
the -(2) is being interpreted as Minus 2 and going backwards in the image array.
when you upload images you should avoid using file names that contain hyphens and parenthesis. i bet if you rename that image and upload it again, it will not have the same problem.
