Buy the ebook version from Amazon, use Calibre ebook library software in combination with Kindle for PC or Mac software and a DeDRM plugin to convert the ebook to htmlz format. Open the .htmlz file with 7zip or other archive program and put the image folder where it's useful to you. Some homework will be needed to configure Calibre, DeDRM, and Kindle to work with each other. Follow the guide on Calibre's website; go slow to move fast.
The images aren't the best resolution, a single figure like the one in the question is only 200 pixels to a side. You'll also need to rename the files manually as they're sequentially numbered, but not in the same order as they appear in the book.
It's a hassle but not too bad of a time and money investment (for me). Less than $20 for the book and a couple hours research and computer futzing. Beats taking the paperback book and cutting the illustrations out, which is what I was going to do if I didn't find a digital solution. (As others have noted, the text is less accurate than the illustrations.) Now I have pictures I can easily re-arrange into a personal study guide in a way that makes sense to me.
Note: breaking digital rights management (copy protection) isn't piracy when it's for personal use. It would be if I turned around and put the results up on an web site for others to download. That's not what's being advocated here.
