GreasyFork fought their advertisers and lost, so anonymous users have to use the new mirror site for "adult" scripts. Eza's Image Glutton didn't disappear or anything! Users with GreasyFork accounts can still see all scripts on GreasyFork if they change their account settings.
Weirdly, Eza's Tumblr Scrape and Eza's Pixiv Fixiv are still on GreasyFork (linked at the bottom of that SleazyFork account page) because Tumblr and Pixiv are not "adult." Okay. Sure. If you say so, advertisers.
Eza's Image Glutton still redirects from pages with a single image to the highest available resolution of that bare image file. Simple and clean.
Eza's Pixiv Fixiv simplifies the "manga" view, loading high-res images when the page loads instead of when you scroll to them, and offering linked thumbnails at the top of the page. It now also intelligently resizes images to fit your screen, and has buttons for different size options.
Eza's Tumblr Scrape finds all images on an entire Tumblr, to download or browse without endless scrolling. It now includes links to videos and removes duplicates when browsing.
All of these work with the Greasemonkey and Tampermonkey extensions for Firefox and Chrome. Questions and comments are encouraged.
