Personally it surprises me that anyone can make a post that includes images and not even just a glance after to see if all is okay!
Yes, as previously said, that particular domain (sites) is problematic and it is why I don't allow it on my site either (for hotlinking).
Why are you posting a private PM I sent you! Even if you have blacked it out. You should have asked me first where I would have said no. That's naughty. All I did was ask if was possible to look at your site as you had mentioned it in a few posts! @ Mods - Remove that image plz.
