Peony extension to mass resize or rotate images

 Peony is the official file manager for the UKUI desktop. This
 package adds extended functionality to the Peony file manager.
 .
 This package adds a "Resize Images..." menu item to the context menu of
 all images. This opens a dialog where you set the desired image size
 and file name. A click on "Resize" finally resizes the image(s) using
 ImageMagick's convert tool.
