If we could make @value work properly in the first argument of @image,
then this could be used to configure image resolution.  So you
would do

@image{../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg.@value{imageres},,,,.png}

and elsewhere do

@set imageres high

to look for a file

../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg.high.png

I will look at the @value issue.
