Hotlinked images from imageshack come and go pretty much at random (all three are showing up fine for me in the posts above, but in the OP I can only see the flumph for some reason); it might be worth saving them again elsewhere. I personally use photobucket for all of mine, it seems pretty reliable. Always good to have a backup anyway in case the original uploader ever deletes the files.
EDIT:
I totally agree.
