eps file

[ming tsang]

Dear lilyponders,
How can I specify the eps file that will be recognized by the \markup - re
below lilypond code? The eps file is in my computer folder.
Shalom,
Ming

\markup {
  \general-align #Y #DOWN {
    \epsfile #X #20 #"context-example.eps"
    \epsfile #Y #20 #"context-example.eps"
  }
}
