Sadpanda is very reliable on a Ps3, that's why I bookmarked it. Whenever people use other sites it almost never shows up and gives the little red "x" square. Sometimes it even gives my Ps3 a difficult time loading that I have to turn it off and on.
Most often, SadPanda doesn't load unless you refresh the image.
For Imgur problems, I just right click and choose "Open Image in New Tab" in Chrome for direct links and "Open in New Tab" for thumbs. It's not really that hard.
