Click on the icon above the text box that looks like an upside-down envelope next to the blue ball. (Mouse over it, and it will say, "Insert image URL."
Then paste the URL of the image there.
If you want to post a picture file from your computer, You could post it first to PhotoBucket, then do that "insert image URL" thing, or you could use the "Post a File" function and do the "insert image URL" thing. The button for "Post a File" is in the menu on the left, in the "Contribute" box.
