Hmm... The images I included in the post aren't showing up, but I've just discovered that the website in question doesn't allow hotlinking, which explains that mystery.
I've changed those to hyperlinks, but you'll have to click on "Open in new window"to bypass the hotlink problem.
The rest of the site is working fine for me at the moment (1:10 p.m. GMT). Maybe it was down for a while.
Let me know how you get on.
