    Default CSS Image Gallery - show image when page loads?

    1) Script Title: CSS Image Gallery

    2) Script URL (on DD): http://www.dynamicdrive.com/style/cs...image-gallery/

    3) Describe problem:

    I really like the simplicity of this image gallery, but I was wondering if it was possible to have one image display when the page loads.

    Thanks,

    Andrew

    Well, with a bit of javascript, yes. Here is an example using the demo code for this css effect:

    Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">
    <html>
    <head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <base href="http://www.dynamicdrive.com/cssexamples/" />
    <style type="text/css">
    
    /*Credits: Dynamic Drive CSS Library */
    /*URL: http://www.dynamicdrive.com/style/ */
    
    .gallerycontainer{
    position: relative;
    /*Add a height attribute and set to largest image's height to prevent overlaying*/
    }
    
    .thumbnail img{
    border: 1px solid white;
    margin: 0 5px 5px 0;
    }
    
    .thumbnail:hover{
    background-color: transparent;
    }
    
    .thumbnail:hover img{
    border: 1px solid blue;
    }
    
    .thumbnail span{ /*CSS for enlarged image*/
    position: absolute;
    background-color: lightyellow;
    padding: 5px;
    left: -1000px;
    border: 1px dashed gray;
    visibility: hidden;
    color: black;
    text-decoration: none;
    }
    
    .thumbnail span img{ /*CSS for enlarged image*/
    border-width: 0;
    padding: 2px;
    }
    
    .thumbnail:hover span{ /*CSS for enlarged image*/
    visibility: visible;
    top: 0;
    left: 230px; /*position where enlarged image should offset horizontally */
    z-index: 50;
    }
    
    </style>
    <script type="text/javascript">
    if (document.getElementById&&document.getElementsByTagName) {
    document.write('<style type="text/css">'+
    '.thumbnail span#begin {'+
    'visibility:visible;'+
    'top: 0;'+
    'left: 230px;'+ /*position where enlarged image should offset horizontally */
    'z-index: 50;'+
    '}'+
    '.thumbnail #begin img {'+
    'border: 1px solid blue;'+
    '}<\/style>')
    }
    
    function initRemove(){
    var thumbs=document.getElementsByTagName('a');
    for (var i_tem = 0; i_tem < thumbs.length; i_tem++)
    if (thumbs[i_tem].className=='thumbnail')
    thumbs[i_tem].onmouseover=function(){
    if (document.getElementById('begin'))
    document.getElementById('begin').id=null;
    }
    }
    
    if (document.getElementById&&document.getElementsByTagName) {
    if ( typeof window.addEventListener != "undefined" )
        window.addEventListener( "load", initRemove, false );
    else if ( typeof window.attachEvent != "undefined" )
        window.attachEvent( "onload", initRemove );
    else {
        if ( window.onload != null ) {
            var oldOnload = window.onload;
            window.onload = function ( e ) {
                oldOnload( e );
                initRemove();
            };
        }
        else
            window.onload = initRemove;
    }
    }
    </script>
    </head>
    <body>
    <div class="gallerycontainer">
    
    <a class="thumbnail" href="#thumb"><img src="media/tree_thumb.jpg" width="100px" height="66px" border="0" /><span id="begin"><img src="media/tree.jpg" /><br />Simply beautiful.</span></a>
    
    <a class="thumbnail" href="#thumb"><img src="media/ocean_thumb.jpg" width="100px" height="66px" border="0" /><span><img src="media/ocean.jpg" /><br />So real, it's unreal. Or is it?</span></a>

    </div>
    
    </body>
    </html>
    Simply give the span that you want visible the id of "begin". In browsers without javascript enabled, the css effect should function just as it would without these modifications.
