How to Quickly Resize Multiple Photos in Mac OS X Using a Terminal Command

Michael Zhang:

If you use a Mac and regularly need to resize batches of photos, there’s actually a tool built into your operating system that lets you do just that without having to open any image editing program. It’s called “sips”, which stands for scriptable image processing system. It’s extremely easy to use, but you’ll need to know how to use Terminal to take advantage of it.

Fast and Easy, Happy Thanksgiving.
