Orientation
Change the orientation of your image, by either flipping along its axes or rotating around the center.
Flip &flip
Mirror the image vertically (up-down) about the x-axis. This always occurs after rotation, if any.

Flop &flop
Mirror the image horizontally (left-right) about the y-axis. This always occurs after rotation, if any.

Rotation &ro=
Rotate the image.
The provided angle is converted to a valid positive degree rotation. For example, -450 will produce a 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.
Images are always auto-oriented based on the EXIF Orientation tag.
