don't view source for images

Viewing image source wasn't working anyway. I have the impression that the
vsource dpi is told, e.g., "Here's 3000 bytes", and then it's only given
however much it takes to reach a NULL in the image data -- but I didn't
trouble myself to dig into the matter, since unformatted image source is
not very informative anyway.
