All I can see in that latest post is a banner stating "No hotlinking", JJ. I thought this was some technical railway term, but Playmofire is correct, it's another photo hosting site block. Also, the pictures in your first post in this topic are showing fine, but not the ones in the second nor fourth posts, unless that is just a glitch with Safari.
Oops, my bad. Firefox shows all the pictures (except the 'No Hotlinking' one), as Playmofire says in the post below.
