Some I'm able to see, others I can't. It only seems to be the ones from that particular site. I even tried to access that site on my phone and still got the same error message. It's weird that if I search for a particular smilie that you've posted in google, it will give that site in the results, but then doesn't work when I click on it (I can see what they are by right clicking and then opening properties.....I can then see the name of the smilie and the link to the website).

It's possible that they are only being wasted on me. Someone else posted a screenshot one time and the picture appeared for them.
