If you are loading from your computer, and you click the image icon (little mountain pic thingy here on the text editor), you may get a box that already has the "http://" in it. Delete this, then paste your IMG box from photobucket. It may look like the paste has doubled up; don't edit it, leave it just the way it pasted. So your pasted image should like http://phototbucket blah blah etc.[url]http://photobucket[/url] blah blah etc [IMG]...
And then you get this:
