How do I get to pull the actual image from the poisonous pile of garbage called imgur? It runs JS from 16 domains.
Use a PC. On mobile it's hopeless - on top of garbage scripts that sometimes lock up even a recent flagship phone, the service does aggressive lossy compression that's hard to work around. If someone uploads an image (whether PNG or JPG, doesn't matter) that has small details like text, forget about discerning them from the blurry mess imgur sends your way.
For single images, imgur will redirect from /<id>.png to /<id> which requires the ton of javascript (you see a message about javascript required to run). Just re-add the extension to the end of the url and you'll access the image directly.
