Is there another location to get the image files?

The image file location www.bignerdranch.com/​downloads/​front-end-dev-resources.zip listed in the book is inaccessible. I’m getting 404 error. With some googling, I found them on github https://github.com/bignerdranch/ottergram-solutions/tree/v1.0.0/ottergram/img.

Is there a new location?
