Change the orientation of your image, by either flipping along its axes or rotating around the center.
# Flip &flipNew!
Flip the image about the vertical Y axis. This always occurs after rotation, if any.
# Flop &flopNew!
Flop the image about the horizontal X axis. This always occurs after rotation, if any.
# Rotation &ro=
Rotates the image by either an explicit angle or auto-orient based on the EXIF
If an angle is specified, it is converted to a valid positive degree rotation. For example,
270 degree rotation. When rotating by an angle other than a multiple of 90, the background
color can be provided with the
&rbg= parameter. See here for the supported color formats.
If no angle is provided, it is determined from the EXIF data.
