Reply To: Working with Grids

That’s a clever way to show an image. You can also just upload an image to imgur.com or dropbox or other sites and insert a link to it here.

That looks like a Japanese writing book. :-)
Personally, I would either make a grid of gray frames using Step and Repeat, or use that script, or just make a single gray frame and then use Step and Repeat to make a series of white lines over it.
