Photos loading sideways on basic templates

Is there any way to upload pictures so they show in the correct position and not sideways? Or maybe a way to just edit the picture so I can rotate it? I've only loaded one picture to my site so far (on my about page) and even though it is saved to my computer normal it is uploaded sideways. I've done this twice and both times the same thing. If anyone could help me I would appreciate it. Thanks!!

What do you mean exactly with sideways? Could you please provide a screenshot of what you see and tell us which browser are you using?
