Hopefully what follows will work:
Wow. After a lot of time I finally managed to get it going so thanks for your help.
For anyone else having difficulty what I put in was the identification of the graphic surrounded by the tags img and /img, each within a set of block brackets. The copied address at Photobucket had some extra formatting which initially blocked the graphic but removing the ?action-view¤t= that was shown in it got everything OK.
Once again thanks to DarthHelmet86 for the help
