||Hi Mark,
Thanks a lot, this was it. With your hint i made a version that can be
called by <<poster>> if tagged as a macro.
\define imgposter(img) [img[$img$]]
\define poster() <$macrocall $name=imgposter img={{!!poster}}/>
Now it would be perfect to be able to set an Imagewidth within this
shorthand like <<poster(20px)>>
My cryptic statement meant that I can't write the code into the field
(like: poster:[img[path]) into the field but just path because it has to
fit into the html videotag
Thanks and Cheers Jan

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.

|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!
- Mark

Hallo!
I want to build a template in which I transclude the imagelinks
stored
in the field poster into an expression that renders the image.
It hast to be just the paths because I also have to use them in the
videotag.
How do you do this?
[img[{{!!poster}}]] [img{!!poster}]?
Thanks and cheers
Jan
