ImageViewer
-----------

This tool lets you view images accessable via any URL supported by your
device.
Which image file formats you can view depends on your device - only
PNG-images MUST be supported by any device, and since current devices will
most probably not support any other formats (like JPEG or GIF), you should
convert the images you want to view to PNG.

Usage:
When you start the program, a (initially empty) list of images shows up.
You can delete, alter and add new URLs of images to that list by using
the menu commands.
When you add or alter an URL, you may alter the describtion label of the URL
and the URL itself.
By selecting a URL from the list, the application will try to load the image
from the specified URL and display it - You may then scroll across the image
by using the cursor keys of your device.

Notes for Siemens SL4xi users:
- Image files placed in the "storage" subfolder of ImageViewer on the MMC
  card can be viewed by entering "file://<filename>" as the URL.
  Example: If there is an image called "example.png" in the "storage"
           subfolder, the correct URL of the picture would be:
           file://example.png

- The screen size of the SL4xi phones is 101x80 pixels, 1bpp (Black/white)
  Colour/Greyscale pictures will automatically be dithered when viewed, but
  they look better if you dither them yourself.
  Do yourself a favor, dither them down to 1 bit per pixel before viewing
  them on the phone - it will shorten the image size and the time to load
  the picture as well.

- The SL4xi phones currently (with firmware <= v54) have a bug (in fact, they
  have dozends :-( ) with the handling of large images - so if your images
  looks wrong, you'd better try to scale it down.
  Furthermore, I recognized that large image files (exceeding 15KB or so)
  will cause the application to crash (which seems occur as soon as you try
  to instantiate a simple 18KB sized byte[] vector, for the developers around
  you)
