Old Issue and GPack answered in comments already that the file in question does not seem to exist (nothing wrong with code above),

however I arrived here due to the title "How to send a variable along with the redirection in node js" and have since discovered the answer to my problem.

If someone ends up here for same reasons as I do then my problem was that I was using

res.redirect instead of res.render("galleryfocus", { image: image });

app.post("/galleryfocus", function(req, res) {
  var image = req.body.imageName;
  console.log("image is:", image);

  res.render("galleryfocus", {
    image: image
  });
});
