Just in case. Gallery Swallower is a userscript for plugins like GreaseMonkey or TamperMonkey, and works on a wide variety of art sites. Dozens of image links can be loaded onto one page for more convenient browsing, comic-reading, and bulk downloading. Fetch rates are kept reasonable to keep servers happy. (But also check your settings in DownThemAll or whatever.)

If you prefer to middle-click every thumbnail yourself, Eza's Image Glutton redirects from any single-image page to the actual image, in the highest available resolution. This works nicely with Double-Click Image Downloader, which is called that for a reason.

Between e621's recent shenanigans and whatever happens next - never trust the cloud. Storage is cheaper than a time machine.
