i do notice in the thread they are sideways but if you click on them to make it bigger its the correct way. if you are referring to the signature.. can't help you there. are they the same orientation that they were taken in or do they just make them sideways? I just started using the attach file option so haven't used tiny pic since then. are you doing it from mobile? could be a bug and finding a contact support might be your best option there
