I would like to force line wrapping if the comment text is of greater width than the image itself. I'm still thinking about how to do this, though, since the images are created on the fly.

The only way to do this is to set the width of the surrounding div to slightly more than the width of the image. You could use javascript for it, but there is no pure css way to create what they call a "shrink wrap" effect.

The width of the image is the variable I want to get at. As you know, the image is generated within the div on-the-fly from php, so I am not sure if information about the width of the image is available at the time that the div is constructed.

Is this inaccurate?

Thanks, Kirby. I had been intending to request that.

The other issue I am pondering with the diagrams is the "Show Diagram Code" text that includes smileys. When we get the text for processing go diagrams, smileys have already been substituted in so the smileys show up in the code text. I'm trying to think of an easier way to show the original diagram code than manually parsing all of the text for every smiley we've added.
