I don't understand what you mean by "it has to be just the paths".
The following will show an image stored in a poster field.
\define imgposter(img) [img[$img$]]
POSTER: <$macrocall $name=imgposter img={{!!poster}}/>
Transclusion's are not real "Things", or at least that's not how they seem
to work to me. They're kind of like asking the waiter to bring you a piece
of toast, and instead he brings you a picture of a piece of toast. So, you
can't really pass the result of transclusion, but instead you pass
instructions for making the transclusion into an entity (a macro) that can
combine the transclusion instructions with other instructions.
The two ways that I know of to accomplish this is by using a set widget to
set an environment variable, or by using the macro call widget to set a
macro variable.
Basically, whenever you find that you want to "pass" the results of a
transclusion to something else (like an image clause), you almost always
need a macro, where the results are passed as the argument in a macro call
widget, or first set as an environmental variable using Set widget.
I may not be understanding this properly, and would be open to a clearer
explanations and/or techniques for dealing with problems like you've
outlined here.
Good luck!
