Automatically Arrange Images in a Grid in InDesign

I didn't think I would be making another post today, but I just learned something MIND-BLOWING.

In InDesign, if you do Place using a number of images, then hold option-shift, you can automatically place those images in a grid. You can even use the arrow keys to decide how many rows/columns you want! I found out about it from here. 

It's PERFECT for storyboards. I worked on boards today and instead of taking 30 minutes to arrange them on a page it took less than a minute. I'm in love. Here are the boards. Hopefully I'll have more boards to show on Thursday.
