Given the difficulty of intercepting it, what are our best options (if any) for getting a decent picture of it? Obviously any data ata ll will be interesting, but I mean something better than a couple of pixels that require a degree in astrophysics to properly appreciate.

Not possible. The least-baddest option I've seen proposed is the Juno probe around Jupiter, but it doesn't have the fuel onboard to achieve the needed velocity, and apparently also had some engine trouble during a previous burn that convinced the team to abort it.
