Yes and no. There's no automated way to do it, but if you can find where a large batch of jpgs are stored it can often be helpful to figure out the array.

For example, by recovering a bunch of files, then adjusting stripe size and recovering them again, see if it looks better or worse. If they all look worse, then try adjusting the stripe size the opposite way. Then, when you find images that open fully and which are larger than the stripe size, check what disks the image spans across to see pairings of drives that clearly follow each other in the rotation.
