Missing pictures

Sorry for the no doubt silly question, but does anyone else see missing pictures? I was browsing around and found a couple of ones where the word link is the only thing that showed up instead of a thumbnail, and when I clicked on the link I only got artists comments, but no picture. I've included three links below of some samples.
