Title: Batch image shrink

It does what it says, shrink a set of images, along the same lines as `batch_image_crop`.

One or two parameters may be specified, `xfac` and `yfac` (optional). If `yfac` is missing, it is set to the same value as `xfac`. For instance:

$ batch_image_shrink 2 3 a.jpg b.png

will create `shrink_a.jpg` and `shrink_b.jpg`. See the man page for more.
