    Hello Jan,
    Thank you for the invitation. But, the file sizes of you pictures average
    about 2 Megs. For some of us they take too long to load even with broadband.
    Simple photo editing software would allow you to get the file size down to
    20 KB and still have good pictures.
    BTW, The first picture is still working on opening.
    I very interested in what you published, but haven't more time,
    Joel Jacobs
