        Moognify 3.0 

        Description:
                Enlarges images with an OS X style effect.
                
        Requirements:

                options - the options
                
        Options:
                duration: miliseconds, duration of the enlarge effect. Defaults to 300.
                borderDuration: miliseconds, duration of the border effect. Defaults to 200.
                borderOpacity: opacity of the image border, defaults to 0.8.
                source: path to the large image. Optional.
                altText: The alt text will be used as image descrition if set to true. Defaults to true.

        Example:
                <img src='imageThumb.jpg' alt='' onclick='new Moognify(this,{duration: 500, source: "imageLarge.jpg", text: "This is one of my pictures."});' />
