I think that you are having a little trouble adding screenshots.
Now of your posts have anything visible in them

But...I can see them with no problem....

I thought that might be the case.All I get is a big empty space.

I had a play around and when I switched off my VPN the pic appeared.
I switched it back on again and everything was OK. So it appears that the VPN connection did not like them although switching it off and on again cured that problem.

So it would seem that it was nothing that you did wrong.

Thanks for the clarification Steve !!
