I have actually been wondering if there are some good non-filejoker sites. I really like the variety and organization here, but the free tier of filejoker has degraded to the point of being unusable, and use of other hosts seems to have dropped off.
Please do not use ImgRock. They do a lot of sleezy things with ads opening windows, auto-redirects, and autoplaying ads. If you block their ads they block the image content.
