Hopefully I didn't come off wrong, I wasn't trying to be the blogging police. I just didn't want a couple of random websites getting credit for images that weren't theirs.
I found the HugelKulture articles at the two websites you sourced and it appears that they are using the the images without stating the source (there were a whole bunch of other articles doing it too) so I can understand the confusion. I would hope that if I make an honest error like this someone would point it out so I can correct it. You can still edit your article (up to 7 days) to include the book as the source.
Off the top of my head I would just site it like this:
Image Source - From Sepp Holzer's Permaculture By: Sepp Holzer
I'me sure that's not the perfect way to site an image from a book but at least people are pointed in the right direction. There are resources online that have detailed instructions on how to site parts of books.
I usually avoid grabbing random images off websites just so I don't run into an issue like this. You can find copyright free images that are suitable for most topics on pixabay, unsplash and on google if you search then select >images>tools>usage rights>labeled for reuse.
For example I found this one that way.

At first it did feel a little like the blog police knocking on my door. But no worries I understand where you were coming from.
Thank you for helping a noob out. I'll resource the pic in this post and check out your recommendations when I need to get a photo that I didn't take. Thank you for responding @canadianrenegade .
No problem, I wouldn't have upvoted and commented if I didn't enjoy the article. ☺️
