That's ok not a
problem, sometimes photobucket can be a bit funny like that, I've had a look at your for sale ad and I've noticed you've got the first image right not a
problem but the others aren't quite right because you've got the IMG code there but no direct link to the picture.
For example each pic should have IMG code then the title / location of the image in photobucket which is what you'll need to copy / paste across.
I believe when you look at the 4 options, if you click on something that's not affecting the page so it won't move the cursor around then double click the IMG code there's normally a small yellow box which comes up and says copied, when you've got that then paste that to your thread and it'll work
