Awesome work here, thank you for providing it for free.
I wanted to read these articles from my phone in offline mode, so I added them to Pocket. Sadly not all the images with the explanations are present in the Pocket article. Writing to you in case you used some non-standard mark-up there, which may be handled differently.
I also did write to the pocket team about this.
