Hello.
A small fix by @jon has been deployed to resolve this issue. It was caused by some odd exif data in the submitted images with conflicting orientation. Whatever camera or utility was used to process these images left an orientation entry for a thumbnail, and a full size but these did not match up and caused problems. We are looking for orientation with more specificity now.
We tracked this open-and-shut ticket as WB-1772. Please let us know if it works for you.
Thanks!
