John down south: A bit of a guess on my part, but there should be a "rotate" function in the photo app. on your hard drive. Did you scan the photo? Maybe there. If you took the all digital route, go to the source and check the camera. The App in Mac is iPhoto. Test the Jpeg you create, to ensure it's upright, and upload to myspace. I don't think the problem is at myspace's end, but I'm not an expert...
