Thanks Anthony I played around briefly with the rotate flag and it seems that the > and < operators don't quite work for me as I want them to, i.e. they don't detect very well when my image needs to be rotated.
But I'll do some more fiddling.

The -90 means rotate anti-clockwaise, use 90 for clockwise. NOTE: this angle of rotate may seem inverted in the mathematical sense, until you realise that the y-axis of images is also negated. That is the Y-axis goes from 0 at the top and positive downward. Thus rotation angles are inverted.
