    javascript not operating . . ?

    I've been looking at this for two days now. I'm fried!

    The javascript routine for the pictures is not functioning.

    I can't see the problem.

        <div class="desc">What is median anyway? To truly understand Mean and Median you really have to look at all of the encompassing data bits. If you have a symetrical set of data, median (mid-pointe) and mean (average) can be very close indeed. However, if the data set is skewed, lets say, by an unusually high sale price, it enforces artificially high mean values with the resulting effect of over pricing. The opposite is true with a low sale price, under valued. Medians have less tendency to fluctuate with excessive real estate trends.</div>

    Alternately, you can try this:

    Code JavaScript:
    <img id="slide" alt="" src="" width="500" height="500" />
    <script> 
    	var step = 0,
    		imgs = [
    			{ 
    				image: 'Arc-Brave.png', 
    				alt: 'Image One' 
    			},
    			{ 
    				image: 'Arc-Dust.png', 
    				alt: 'Image Two' 
    			},
    			{ 
    				image: 'Arc-Human.png', 
    				alt: 'Image Three' 
    			}	
    		];
     
    	// Preload Images
    	function preloadImages(source) {
    		for(var i = 0; i < source.length; i++ ) {
    			var img = new Image();
    			if( source.hasOwnProperty('image') ) {	
    				img.src = source[i].image;
    			}
    		}	
    	}
    	preloadImages(imgs);
     
    	function slideIt() {
    		var slider = document.getElementById('slide');
    			slider.src = imgs[step].image;
    			slider.alt = imgs[step].alt;
     
    			step++;
    			if( imgs.length === step ) {
    				step = 0;
    			}
     
    		setTimeout( 
    			function() { 
    				slideIt(); 
    			}, 
    			5000 
    		);		
    	}
    	slideIt();
    </script>

    Still doesn't work!

    I re did the entire page.

    Validation of both pages below is ok except for the img tag in Strict.

    www.propertieswithstyle.com/cdcdata.html

    This page works flawlessly.

    www.propertieswithstyle.com/cdmdata.html

    The page show fails to show the initial loaded picture or any of the pictures.

    They are the same or - I'm blinded to the error is more likely.

    I don't understand the suggested code and how it is different.

    Thanks much everyone - Rick

    Not a problem, I can go over a revised code of the above to show the example better:

    Code JavaScript:
    <img id="slide" 
    	 width="470" 
    	 height="250" 
    	 alt="corona del mar picture slide show" 
    	 src="http://www.propertieswithstyle.com/css/images/cdmnpthbr.jpg" 
    />
    <script> 
    	function preloadImages(array, url) {
    		// Initialize variables
     
    		// i for incrementing through the array
    		var i = 0,
    			// for the img object later in this function
    			img;
     
    		// cycle through the array
    		for( i; i < array.length; i++ ) {
    			if( document.images ) {
    				img = new Image();
    				img.src = url + array[i];
     
    				// Put the loaded images back into the array so we can access it later...
    				array[i] = img.src;
    			}
    		}
    		// Return the array
    		return array;
    	}
     
    	// Initialize variables
     
    	// for incrementing value in the slideIt function
    	var step = 0, 
     
    		// static variable for the img element where the slide show will be
    		slider = document.getElementById('slide'), 
     
    		// imgs var that is calling the preloadImages(array, url) function
    		imgs = preloadImages(
    			// Array for your images
    			[
    				'cdmpicketfence.jpg',
    				'cdmbelowstreetlevel.jpg',
    				'cdmbigcorona.jpg',
    				'cdmdowncoast.jpg'
    			],
    			'http://www.propertieswithstyle.com/css/images/'
    		);
     
    	function slideIt() {
    		// Set the img element's source
    		slider.src = imgs[step];
     
    		// Incremenent the step variable
    		step++;
     
    		// if the array length equals the step number, then reset step back to 0
    		if( imgs.length === step ) {
    			step = 0;
    		}
     
    		setTimeout( 
    			function() { 
    				slideIt(); 
    			}, 
    			5000 
    		);		
    	}
    	slideIt();			
    </script>

    All I am doing here, basically, is putting the requested images in an array, pre-loading the image, returning the revised array, globally, to the slideIt function.

    By putting the requested images in a array, you lose calling var img1; img1 = new Image(), var img2; img2 = new Image(), etc., then you can put the image pre-loader in a function. You also get the benefit of utilizing the array.length property so you can avoid:
    Code:
    if (step<22)
    By doing this:
    Code:
    if( array.length === step )
    if( array.length < step )
    if( array.length >= step )
    //etc
    I also am using an id for the HTML img tag since name is not a valid attribute as you are aware.
    Code:
    <img id="slide" />
    slider = document.getElementById('slide');
