I just followed the directions above, exactly and was able to get it. Not sure at all what to tell you, or how to help sorry. But I do know it starts with (img) or something like that..then a bunch of numbers and ending in (/img) its going to look something like this:
(img)

The ()'s should be [] instead, but at least you have an idea of what to look for.
Hope this helps
