Here's a couple of ideas:
If the image urls are fetched from an XML file, and the xml is
generated dynamically, have the server write the filesize of the
images into the xml. Or, if the images are added to the xml manually,
add the filesize of each image to the XML.
Or, you could just display a number of total images loaded: "Loading
3 of 15" for example, instead of the total bytes loaded.

Hi Adrian,
thanks for the idea but this approach will not work in my case
because the images are loaded sequencially. If one image is
finished loading, my class starts loading the next and so on, one
after one. And the amount of images varies (the image filenames are
fetched from a XML file).
I'm now defining a segmentWidth by dividing the full progressbar
width by the amount of images that are going to be loaded. That
gives me the 100% for one image on the whol bar. I just haven't
figured out yet how to make it work so that the bar doesn't start
from 0 at every image. Any other idea?

progressbar?
Say you have 3 images loading, use something like this:
var bytesLoaded:Number = 0;
var bytesTotal:Number = 0;
bytesLoaded += image1.getBytesLoaded();
bytesTotal += image1.getBytesTotal();
bytesLoaded += image2.getBytesLoaded();
bytesTotal += image2.getBytesTotal();
bytesLoaded += image3.getBytesLoaded();
bytesTotal += image3.getBytesTotal();
var percentageLoaded:Number = (bytesLoaded/bytesTotal) * 100;
There may be ways to optimise this code depending on your
circumstances (e.g.
just calculate bytesTotal once and reuse it) but this shows the
basic idea.

Hi,
this is probably an old hat but I can't get it right. I want to
display
the
load progress of several images with one progress bar. How do I
calculate
the percentage of the bar?
Thanks alot,
