I think this is really ugly. Your solution should hide the implementation
from the user and should not have sideeffects as changing the attached
files.

Even uglier.

As allready said, make the macro return

<img src="?action=build_png>">

If you don't want to generate the picture every time use
MoinMoin/caching.py

Everything else is a bad hack!
