Picture

The following partial example adds a picture at the end of each chapter:

\definecounter[EventCount]
  [
    way=bytext,
    prefix=no,
  ]

\startTEXpage
  \incrementcounter[EventCount]
  \externalfigure[{\rawcountervalue[EventCount]}]
                 [
                   height=\paperheight,
                   orientation=90,
                 ]
\stopTEXpage

The pictures are numbered sequentially, starting at 1.

Show Section Number

The following example writes a counter in a layer:

<texcode> \definecounter[MyCounter][

 way=bytext,
 prefix=no

]

\setnumber[MyCounter][0]

\setuphead[section][

 page=left,
 before={\incrementcounter[MyCounter]},

]

\definelayer[MyLayer][

 width=\paperwidth,
 height=\paperheight,
 position=no,
 repeat=no,

]

\setupbackgrounds[page][

 setups=MySetup,
 background=MyLayer,

]

\startsetups[MySetup] \ifnum\rawcountervalue[MyCounter]>0

 MyCounter = \rawcountervalue[MyCounter]

\fi \stopsetups

\starttext

 \startsection[title=S1]
 \stopsection
 \startsection[title=S2]
 \stopsection

\stoptext </textcode>
