Gary Lucas commented on IMAGING-319:
------------------------------------
I will take a look. I've been away from Commons Imaging for awhile, so it's
going to take some time to get set up again.
As I recall, the code fix worked for the sample submitted by the original
author. Perhaps something has shifted in the code base since then. I'll also
look at pull 275.
If you have any recommendations, please let me know.
