Remember that JavaScript is a programming language after all.  You can use a
loop to get rid of the repetitions.
Start from
var done = ["load", "error", "abort"]...
and apply the closure image.aEL(?, hPB, false) to it.
Sincerely,
Chris

==========================================
function showImage(imageHref) {
...

// remove the progress bar when done.
       image.addEventListener("load", hideProgressBar, false);
       image.addEventListener("error", hideProgressBar, false);
       image.addEventListener("abort", hideProgressBar, false);
}
==========================================

This is somewhat verbose. Clearly, the author is forced to repeat
himself when all he really wants to do is hide the progress bar after
the call is done.
