Silly question, but I've just received a photo sent as attachment to an e-mail. It's sideways. I'm sure there's a way of turning it upright, but I've forgotten how. This computer is Windows 7 but my other one is Windows 8, so I need this for both.
I have windows XP but it might work
in win 7 or 8.
Save the attachment to somewhere
like your documents file.
Then open it in windows media player.
You should be able to rotate it in there.
I hope it works for you it does for me.

Save the attachment to your computer. Then find where you saved it, and double-click to open it. It should open in Windows Photo Viewer. You will be able to rotate it there.
