Go to GitHub and use digital criminals OF scraper. It does require u to log in to your account in chrome and then taking your session data and putting it into a config file. Its a bit of fucking around using python, but I have zero coding know how and got it working in under 10 minutes - there's a good quick YouTube tutorial by a dude off raidforums if u Google it. The browser add ins / extensions are all based off this original code. But be wary, there was some discussion that either the original code or the "forks" that used the source code to create these plugins were sending your session cookies to the creators which would allow them to access your OF account. However the author on GitHub is quite clear this isn't happening with his code, so perhaps others have added it since. I personally have had no issues running it in python, no abnormal logins and I've scraped all of my subscriptions easily over the last few months. And session cookies only work whilst you're logged in, so log out once you're finished scraping.
I think the browser extensions require you to go to the bottom of each page and wait for everything to load (which can take forever for a creator with thousands of posts). The GitHub one just does it all from command line and u can download everyone at once. There's some people who have made some GUIs to make it more user friendly, but I haven't looked into them.
The difference between this scraper and using those other image downloaders mentioned, is those image downloaders aren't very good at getting the full sized images, sometimes it just gets the preview which is slightly cropped and even misses some of them. The scraper gets the highest quality version available, which often even has all of the original image meta data still attached (like GPS location, camera etc.). Discovered one quite big creator lives about 300m from me
OF did update their terms of service not all that long ago to say that you aren't allowed to use scrapers, so if they eventually install some sort of scrape detection you do run the risk of being banned.
