it depends how you shot it. the camera has an orientation sensor in it, and it tells the camera and windows what direction the image is in. however depending how you shot it, it may have shown it right. like pointing straight down does odd things.
in any case, thinking about it won't fix it, you'll have to fix and upload or you'll look silly in front of buyers. and the hooks would be on the wrong ends.
