The aim is to not need to define a filename for each image, to minimise 
the boilerplate. Org has a mechanism for this, but it only works when 
Org creates the file.

Using a combination of noweb and file header arguments, with a property 
drawer, I was able to have each code block only require a unique name 
and the image code. That is except, because the image library creates 
the file, I need to specify a var to give a filename. Hence, I poked 
around until I found a way to use the computed filename.

While I'm happy with the solution I found, as a novice Org user, it 
seemed like I needed to reach into undocumented internals to do this. So 
I queried this, partly to understand if there was a better way, and 
partly to see if it was worth providing a better way or at least 
documenting a method.

Based on your response, maybe I'm doing something unusual. In which 
case, it's not surprising I couldn't find a more obvious way.
