variant to json.vi not supported on RT due to picture

[AndrewHeim]

The "variant to json" VI is broken when I put it on a cRIO. The reason is the picture case includes a VI that isn't supported on that target. I've had to diagram out that case in my build... but then rebuild the package for the others on this project. So if it's that bad, it should be here.

If I needed picture support I might be able to justify spending time on it - but I can't for this project.
