I described it in the instruction pastebin: "... downloaded from qanon.pub using the "save as" option of the Opera browser after slowly scrolling through the whole website so that all images are loaded and displayed."  That takes a while (half an hour with a slow internet connection) and then I compare with previous versions to make sure no file is missing. The Opera browser (on a 64-bit system) has a good memory management to handle such a large html page. For other sites I use some spider software. For example I used "Cyotek WebCopy" in that case (wikileaks subdirectory): https://voat.co/v/GreatAwakening/3945805/
