I've been experimenting with the /picture endpoint in R2 which works fine. But if I use this for an earlier version of 2014, I get a 13KB java dump unlike the simple "NOT_FOUND" I get for an invalid endpoint on R2. Is there any way to obtain version information via REST which will allow me to determine if the 2014 version I'm dealing with supports /picture?

I have yet to try adding a picture via the API, but it would be useful to know the required format and dimensions in pixels.

Thanks, John
