There are two ways of rotating a picture. Transposing each pixel so that they are saved in the target order or just setting a flag in the header to let the displaying software know that it should rotate the picture to display it. Most cameras do the second one. Unfortunately, TMO's picture uploaded does not understand that flag and you end up with pictures turned sideways like yours. The only way to fix it is to rotate it in some picture editing software before uploading. Been there, done that.
