Hi imagemagick users I've done some more testing using the rotate flag and I've found that when using -rotate '90<' all the images that should be portrait go landscape and vice versa. When using -rotate '90>' nothing happens i.e. the images don't rotate at all, whether they are landscape or portrait. Odd...
Any ideas? It almost seems like the > flag is broken? Any other way for me to make landscape images portrait?

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.
