[Workbook resources not found on the web]

Thanks to you all, for your prompt replies. Unfortunately none of them worked, but they stimulated me to try something else. I typed the affin.co link into my Samsung Galaxy Tablet, and the Mam Tor zipfile came down. The tablet said it couldn't handle zip files, but I successfully copied the download to my Samsung laptop, Windows 10,  and I was able to open them. I can't understand what went wrong, but I'm very happy to have found a way of getting the resources. It takes only a couple of minutes. 
Many thanks again. At least I now also know how to use this excellent Forum. 

[Workbook resources not found on the web]

There may be a simple answer. I'm trying to use the Photo Workbook, but I'm unable to obtain the resource images, e.g. from https://affin.co/photofeatures. Can anyone help?
