The reason why you are having problems with the "document..." is because you
are probably calling the edit handler for the image twice or passing more
than one object
id to the edit handler. I faced a very similar problem and even created my
own version of the image
object. My version pretty much mimics the spectra version, but I added some
more functionality. It works
great if I call the edit handler once, but gives me the same javascript
error if I call it more than once.
Once I have that solved, I will go ahead and let you know.
