You can rotate some products, but not the graphic as far as I know. Like the phone can be made vertical etc. But if your image is the wrong direction you have to correct for that.
I also don't think you can have the image on both sides unless you follow the template and create a banner shape that has the image on both sides. A bit of a pain but, it is what it is. The site is mostly set up for prints, so things like adding more than one image on something, we don't have that. Yet. Unless we do, and we weren't told, there are at times easter eggs on the site.
