The error message tells your that the conflict is not caused by
the modification of the image but the container holding your image.

"BTreeFolder" already do conflict resolution -- and reduce the
conflict probability by about a factor of 30 to 100 (depending on type).

However, if several threads should try to add elements with the same
id, then the conflict resolution cannot work.
Maybe, that happens in your case?

The id for the image object is generated by the following code:

def MakeId():
ts = string.replace(str(time.time()),'.', '') # remove floating point '.' char
  return ts[-10:]

So there should not be any collision of ids.
