Photo added to profile

I need a little help. I'm trying to add a photo to my profile and did so successfully. The issue is the photo is in the wrong orientation (sideways). When I try to post the same photo with the correct orientation (top to bottom) as a replacement, nothing happens. Why and how do I fix it?

Also, how do I get the photo to display with each forum message i submit?

Thanks,
