Hey Randall,
Sorry for the delay in replying. Summer vacation! The issue that I was having is that the documentation said that comma delimited was OK, but I subsequently learned that it had to be piped. My struggle now is, I believe to be the accuracy parameters, which seems to be comma delimited.
To answer your question I am looking in the log folder under OrientatedImagery. In the XML files you can see what goes wrong. However, the answers are a little terse and it takes a while to iterate to a solution!
I think I would be a lot further if the tool had examples of each image import type. In my case I went for a Frame Table and in the ESRI documentation there are two table definitions! Trying the first one did not work at all.

p.s. We have defined the X, Y, Z and SRS and the CamOri to stop the code from complaining.
