I doubt that you can do that in plain metapost (maybe I'm wrong), but
you can use metafun.

For example:

\starttext
\startMPpage % or \startMPcode
    externalfigure "filename.png" xyscaled (300,200);
    % normal metapost code goes here
\stopMPpage % or \stopMPcode
\stoptext

which has to be compiled with "texexec filename". See metafun manual
for more details:
