In context/metapost this is possible:

\setupoutput[pdftex]
\setupcolors[state=start]

\starttext

\startMPpage[offset=1pt]
     externalfigure "hacker.jpg" xscaled 5cm yscaled 4cm ;
     picture p ; p := btex TEST etex 
xysized(bbwidth(currentpicture),bbheight(currentpicture)) ;
     draw p shifted (center currentpicture - center p) withcolor red ;
\stopMPpage

\stoptext

if you use another macro package, you can still use context to make independent 
graphics and then include them as pdf graphic
