Have used wget before but always with hesitation because the options don't seem to always do the expected.
When testing your suggested wget + parms I don't see any images being downloaded…?
Can you speak to this and recommend a fix?
On Dec 17th someone sent me this wget command which scrapes all the images referenced in a single thread:
wget -P ./thread/ -nd -r -l 1 -H -D media.8ch.net -A png,gif,jpg,jpeg,webm https:// insert_thread_URL_here.html
and it works but does not fetch the fullsize images, only the thumbnails, and I haven't figured out how to modify your wget mirror -the-whole-qresearch command to also fetch images and adjust references so the local HTML pages refer to locally-mirrored images.
I just don't have the time or patience to work this out.
