Have you got a pile of images you want to rotate or resize? You can do this really quickly on your Mac using built-in command line aka The Terminal in seconds.
Your out-of-the-box Apple Mac comes with loads of powerful tools that you can only access through The Terminal. As deathly final as that sounds, Terminal is a text-based interface to control your computer, manipulate files and run programmes. Instead of clicking or dragging an icon, you type in a Linux command (here's a list of generally useful Linux commands).
In this case a couple of dozen image files needed to be resized and rotated. The sips (scriptable image processing system) command can be used to resize and rotate many many images in seconds as follows:
1) Put all images to be processed in one folder
2) Open Terminal (type it into Spotlight)
3) Change to the images' folder
4) Converts all files to a maximum width/height of 640 pixels
This command line interface is especially useful when you've got more than a handful of files to process in the same way. Sips can do a lot more to your images - check out the full list

This tool is used to query or modify raster image files and ColorSync ICC profiles. Its functionality can also be used through the "Image Events" AppleScript suite.
