Hi Aaron,

thanks for the patch.

What happens when there is :file png with no #+name line?

Does :output-dir accept absolute or relative paths?  I'm asking
because you speak of "subdirectory", but both should be accepted
IMHO.

Maybe there are cases where the :file value does not take an extension
but the user still want to write the output to this file?  How would
your patch handle this?

Looks useful to me, but ":file png" looks wrong, with too much
implicit.  We should find something less confusing.

Thanks,
