Retrieve Images From Server via Client Side

I have a folder on the server with some images in it. I would like to have my client code read this folder's contents (images) and then display this image on a div. I thought this would be easy with AJAX, but it seems that AJAX returns some raw data embedded in the image. I have been looking all over for a way to get the image's url instead of this data, but everything I have tried just does not work. I really prefer to do this on the client side. I appreciate any suggestions you can give me on going about this :).

Thanks,

//Here is some of my code...

var info = new OpenLayers.Control.WMSGetFeatureInfo({
                        url: 'http://localhost:8080/geoserver/wms',
                        title: 'Identify features by clicking',
                        queryVisible: true,
                        eventListeners: {
                            getfeatureinfo: function(event){              
                               map.addPopup( new OpenLayers.Popup.AnchoredBubble(
                                    "chicken",
                                    map.getLonLatFromPixel(event.xy),
                                    null,
                                    event.text + '<div> Hello Tibet :)</div>' + load('./Photos/potalaPalace.jpg'), 
                                    null,
                                    true

                                ));

                            }

                         }
                    });
