    Unhappy Modified snow code...

    Script: Snow Effect
    http://www.dynamicdrive.com/dynamicindex3/snow.htm

    I've tried to modify the script with my own image, but it's not working? Did I enter it wrong?

    <script language="JavaScript1.2">

    What is the location/name of your image - it should be entered at the top of the script. You might also like to look at my site where there is a snow code that has slush too and doesn't rely on images!

    Try to use full path to your image, e.g. http://www.yoursite.com/images/snow.gif
