Hello there: first of all i have no idea on coding or anything related, simple question: is there any simple way to tell this code to autostart the slide? at the current moment the images change on click.
currently the index page only have one image, what i want is to add a few but without the need to click to see the next one
here is the code from my index:
<script type="text/javascript">
//<![CDATA[
/*
the images preload plugin
*/
(function($) {
$.fn.preload = function(options) {
var opts = $.extend({}, $.fn.preload.defaults, options),
o = $.meta ? $.extend({}, opts, this.data()) : opts;
var c = this.length,
l = 0;
return this.each(function() {
var $i = $(this);
$('<img/>').load(function(i){
++l;
if(l == c) o.onComplete();
}).attr('src',$i.attr('src'));
});
};
$.fn.preload.defaults = {
onComplete : function(){return false;}
};
})(jQuery);
//]]>
