    Continuous slideshow of images without loop

    Hi to everyone!

    As it is known from the title, I'm building a web page running continuous slideshow of images, like watching a video. I wrote the header part below:

    <script language="javascript" type="text/javascript">

    var slideimages = new Array()
    function slideshowimages()
    {
    for (i = 0; i < slideshowimages.arguments.length; i++)
    {
    slideimages[i] = new Image()
    slideimages[i].src = slideshowimages.arguments[i]
    }
    }

    </script>

    ...and the following part as body:

    <img src="/sampleasp/foto/10.jpeg" name="slide" border=0>
    <script>

    //configure the paths of the images
    slideshowimages("/sampleasp/foto/10.jpeg", "/sampleasp/foto/11.jpeg", "/sampleasp/foto/12.jpeg", "/sampleasp/foto/13.jpeg", "/sampleasp/foto/14.jpeg", "/sampleasp/foto/15.jpeg", "/sampleasp/foto/16.jpeg", "/sampleasp/foto/17.jpeg", "/sampleasp/foto/18.jpeg", "/sampleasp/foto/19.jpeg",
    "/sampleasp/foto/20.jpeg", "/sampleasp/foto/21.jpeg", "/sampleasp/foto/22.jpeg", "/sampleasp/foto/23.jpeg", "/sampleasp/foto/24.jpeg", "/sampleasp/foto/25.jpeg", "/sampleasp/foto/26.jpeg", "/sampleasp/foto/27.jpeg", "/sampleasp/foto/28.jpeg", "/sampleasp/foto/29.jpeg",
    "/sampleasp/foto/30.jpeg", "/sampleasp/foto/31.jpeg", "/sampleasp/foto/32.jpeg", "/sampleasp/foto/33.jpeg", "/sampleasp/foto/34.jpeg", "/sampleasp/foto/35.jpeg", "/sampleasp/foto/36.jpeg", "/sampleasp/foto/37.jpeg", "/sampleasp/foto/38.jpeg", "/sampleasp/foto/39.jpeg",
    "/sampleasp/foto/40.jpeg", "/sampleasp/foto/41.jpeg", "/sampleasp/foto/42.jpeg", "/sampleasp/foto/43.jpeg", "/sampleasp/foto/44.jpeg", "/sampleasp/foto/45.jpeg", "/sampleasp/foto/46.jpeg", "/sampleasp/foto/47.jpeg", "/sampleasp/foto/48.jpeg", "/sampleasp/foto/49.jpeg",
    "/sampleasp/foto/50.jpeg", "/sampleasp/foto/51.jpeg", "/sampleasp/foto/52.jpeg", "/sampleasp/foto/53.jpeg", "/sampleasp/foto/54.jpeg", "/sampleasp/foto/55.jpeg", "/sampleasp/foto/56.jpeg", "/sampleasp/foto/57.jpeg", "/sampleasp/foto/58.jpeg", "/sampleasp/foto/59.jpeg",
    "/sampleasp/foto/60.jpeg", "/sampleasp/foto/61.jpeg", "/sampleasp/foto/62.jpeg", "/sampleasp/foto/63.jpeg", "/sampleasp/foto/64.jpeg", "/sampleasp/foto/65.jpeg", "/sampleasp/foto/66.jpeg", "/sampleasp/foto/67.jpeg", "/sampleasp/foto/68.jpeg", "/sampleasp/foto/69.jpeg",
    "/sampleasp/foto/70.jpeg", "/sampleasp/foto/71.jpeg", "/sampleasp/foto/72.jpeg", "/sampleasp/foto/73.jpeg", "/sampleasp/foto/74.jpeg", "/sampleasp/foto/75.jpeg", "/sampleasp/foto/76.jpeg", "/sampleasp/foto/77.jpeg", "/sampleasp/foto/78.jpeg", "/sampleasp/foto/79.jpeg",
    "/sampleasp/foto/80.jpeg", "/sampleasp/foto/81.jpeg", "/sampleasp/foto/82.jpeg", "/sampleasp/foto/83.jpeg", "/sampleasp/foto/84.jpeg", "/sampleasp/foto/85.jpeg", "/sampleasp/foto/86.jpeg", "/sampleasp/foto/87.jpeg", "/sampleasp/foto/88.jpeg", "/sampleasp/foto/89.jpeg",
    "/sampleasp/foto/90.jpeg", "/sampleasp/foto/91.jpeg", "/sampleasp/foto/92.jpeg", "/sampleasp/foto/93.jpeg", "/sampleasp/foto/94.jpeg", "/sampleasp/foto/95.jpeg", "/sampleasp/foto/96.jpeg", "/sampleasp/foto/97.jpeg", "/sampleasp/foto/98.jpeg", "/sampleasp/foto/99.jpeg")

    //edit frame per second
    var slideshowspeed = 250
    var whichlink = 0
    var whichimage = 0

    function slideit()
    {
    if (!document.images)
    return
    document.images.slide.src = slideimages[whichimage].src
    whichlink = whichimage
    if (whichimage < slideimages.length - 1)
    whichimage++
    else
    whichimage = 0
    setTimeout("slideit()", slideshowspeed)
    }
    slideit()
    </script>
    Here, the biggest problem is, when the page is loaded there are still coming images saved from a capture device. So, my images from the captures device can not be loaded to my web page. I need to pass these images directly to the web page as real-time video taken directly to the web page. Please help!

    I solved the problem. Continuos time playing is possible. However, there is another problem nonrelated to the above code:

    While web page is loaded from the client side, I cannot delete the web page file (MyPage.aspx) from the server side. I need to update (renew) the web page from server side by using a C# program in order to start the slides from the latest images created from the server side.

    To do that, first I delete MyPage.aspx and then copy the new MyPage.aspx file.

    File.Delete("C:\\ServerRootLocation\\MyPage.aspx");
    File.Copy(Application.StartupPath + "\\weblist\\MyPage" + weblist_count + ".aspx", "C:\\ServerRootLocation\\MyPage.aspx");

    How can I do that?

    A better solution is to use AJAX to call a script that returns the "latest" photos.
