In order to do this with buttons, you need to create the resources (an x 
object will do)' in context this is implemented as follows:

% output=pdftex

\setupinteraction
   [state=start]

\setupcolors
   [state=start]

\setuppapersize
   [S3][S3]

\setupbodyfont
   [17.3pt]

\setuplayout
   [width=middle,
    header=0pt,
    footer=0pt,
    width=middle]

\defineframedtext
   [sample]
   [background=color,
    backgroundcolor=darkgray,
    width=4cm,
    height=4cm,
    align={middle,lohi}]

\definesymbol[N-ONE]  [\sample {\red     Some Kind Of Image}]
\definesymbol[N-TWO]  [\sample {\green   Some Kind Of Image}]
\definesymbol[N-THREE][\sample {\blue    Some Kind Of Image}]

\definesymbol[Y-ONE]  [\sample {\cyan    Some Kind Of Image}]
\definesymbol[Y-TWO]  [\sample {\magenta Some Kind Of Image}]
\definesymbol[Y-THREE][\sample {\yellow  Some Kind Of Image}]

\definefield
   [test] [check] []
   [{N-ONE,N-TWO,N-THREE},{Y-ONE,Y-TWO,Y-THREE}]

\starttext \field[test] \stoptext

the field commands work together will the context symbosl mechanism; and 
symbols can be anything (graphics included);

The up/down etc modes are supported by the commalists.

BTW, there is a roll over buttn feature in context but not yet in the 
public distribution,
