[texhax] labeling images with text

[Erin Glaser Arlinghaus]

I'm interested in importing graphical diagrams as *.eps files in the
"normal" way, but inserting text into the diagrams (e.g. labeled arrows)
with LaTeX commands (so that I could easily change the labels without
having to edit the *.eps files).  I was thinking that the way it might be
done is to somehow create a graphic, with text boxes here and there as part
of it, that had an *.eps file as its background.  But I can't figure out
how to do this, or even where to look for instructions.  Am I on the right
track?  Is this possible?  Where can I go for help?
