An anon posted this script that will auto block images that you mark as spam. I know it's been around a long time but I hadn't tried it before, and then couldn't find it when I wanted to Reposting in case it helps anyone else. You can paste it into Options-UserJS.

Before and after screenshots attached. When I use this along with certain Comments in Options-Filters, I enjoy life here a lot more. (But a salute to the anti-filter anons out there too, who can stand to look at the same spam in every bread.)
