This plugin will automatically re-orient a picture when it is uploaded.

It uses the 'auto-orient' function of ImageMagick th read the orientation data
and rotate the picture appropriately.

Prerequisites :
An installation of ImageMagick that Coppermine is configured to use.
This version of ImageMagick must have the 'auto-orient' function.

Caveats :
All uploaded images will be submitted to ImageMagick for rotation, this could
result in a degredation of image quality.

This plugin has only been tested on a Linux based server.

I do not know what version of ImageMagick introduced the auto-orient function.
