Hi Colin
I think that you pictures might be too big for the forum to load.
Sprocket posted a good Set of Instructions on how to post pictures successfully.
What I tend to do is post the direct link from Photobucket on this website
I then after posting click on the link and copy and paste the pic under the edit button
It works every time
Like this: http://i126.photobucket.com/albums/p84/johng_016/vic-ephesus-turkey.jpg
Now highlight and Copy and Paste
