Many links are broken or dead.
Not many, just three. In fact, these three links are from the Castlevania Crypt, and that site won't let images be linked anywhere. This happens in Google Images too - if you look for a spritesheet on Google images, clicks on it and it takes you to the Castlevania Crypt, then it'll say "Not Found". But if you try getting on these images through the Castlevania Crypt site, then it'll work. The links with these issues are:

Nintendo Power preview part 3 + IGA interview
Now, Nagumo, remember how I said certain images linked on your post are appearing very small? This is happening because the URLs you used have something like "/revision/latest?cb=20130314043855" after them. For instance:
http://vignette3.wikia.nocookie.net/castlevania/images/8/83/Dengeki-scoop1.jpg/revision/latest?cb=20151203044254Removing this last part, right after the "jpg", fixes the issue, and the images appear big as their normally would. Could you please do that :| ? The links with this issue are:
