I show you how it’s done without problems on a simple example.

All your files are in directory with the two subfolders “tex” for for subparts
of your document and “graphic” for figures.

  relabs.tex
  relabs-environment.tex
  tex/pickedup.tex
  graphics/pic.pdf


The content (i attached all files) of the tex-files is:

<file name="relabs.tex">
\startproduct relabs

\environment relabs-environment

\section{Graphic}

\placefigure[force]
  {A Graphic}
  {\externalfigure[pic]}

\section{File}

\component pickedup

\stopproduct
</file>

<file name="relabs-environment.tex">
\startenvironment relabs-environment

\doifmodeelse{*product}
  {\setupexternalfigures[directory={graphics}]}
  {\setupexternalfigures[directory={../graphics}]}

\usepath[tex]

\stopenvironment
</file>

<file name="pickedup.tex">
\startcomponent pickedup

\environment relabs-environment

\subsection{Text}

\input knuth

\subsection{Graphic}

\placefigure[force]
  {Another graphic}
  {\externalfigure[pic]}

\stopcomponent
</file>


I used product and component because you can now set different figure
paths for both files. When you process the product context should search
in the “graphic” folder which is in the same folder but when you process
the component context should first go into the parent folder and then
look in “graphics”.


For the inclusion of files you can specify with “\usepath” where context
should look and all you need as argument for \component is the name of
the file.
