Forum:How to make a Speech Arrow

On a new page I am working on on another Wiki I want to add a Speeach Arrow ( like those that go from profile pictures to avatars on comments ). I would like an "arrow" to go from an image of a person to a div box so that it appears the image has a speech bubble of some sort. Is there anyway I can do this?

It would be much appreciated if someone can help me.
