Glad you told me it was sideways, as I couldn't figure it out!! If you're taking a picture with an I-phone, best to just take in landscape mode (wide, versus tall), as you CAN fix the picture if it's taken the other way, but it's fairly complicated. Pictures posted directly in a thread like this one(versus using the IMAGE tag), a person can rotate them to look at them, but there's no way to make the picture stay rotated.
