Now that we can't futz with forumtext, it's irritating that once we have a forum image, we can never remove it completely — only change it.
So this is just a suggestion for an option to remove it.
Either a sort of 'clear form' button to remove all of the choices or a radio button choice of 'none' with the right, top, and bottom options would be great.
Yeah, I've been having the same problem, too. I'm hoping it was just a simple oversight or a bug that has yet to be ironed out.
There's a button on the page for removing images now. :)
