thats what i already have:

...

\startsetups btx:duane:cite:filename {\btxfield{url_image}} \stopsetups

so you mean i have to use btxfield outside a setups? what seems strange to me is that \cite[filename] works as such, but not as an argument to \externalfigure i thought it might have to do with the data (url_image) not being available in the first pass. thanks michael

Could somebody explain me why this (the part that is commented) doesn't work? I get the following error:

tex error > tex error on line 0 in file : ! Emergency stop <*> cont-yes.mkiv <empty file> *** (job aborted, no legal \end found)

because \cite does a lot more than just returning a filename ... you need to use the low more level btxfield commands to get the more raw data

Thanks Michael

that's what I did at first: \startsetups btx:duane:cite:external {\externalfigure[\btxfield{url_image}][width=10cm]} \stopsetups the problem is that I need the control the width of externalfigure in the text. With the above solution I have to define a different cite rendering for every possible width I need in my layout. Isn't there a way to just get the filename of the cite so I can a macro with the width as an argument? Thanks Michael

The \externalfigure tries to do quite a lot with its argument(s).

You can use \placecitation [duane::tug2014] defining your rendering appropriately to call \externalfigure.
