 With a simple map containing only an image layer and no controls, error
 occurs in Layer.image.js when browser is closed.

 {{{
    function init() {
       var map = new OpenLayers.Map( 'map', { controls: [] } );

       var baseLayer = new OpenLayers.Layer.Image('Image',
 'images/whitepixel.png',
          new OpenLayers.Bounds(-180, -88.759, 180, 88.759),
          new OpenLayers.Size(512, 512), {numZoomLevels: 3});

       map.addLayer(baseLayer);
    }
 }}}

 Layer/Image.js line 70-74:

 {{{
    destroy: function() {
       this.tile.destroy();
       this.tile = null;
       OpenLayers.Layer.prototype.destroy.apply(this, arguments);
    },
 }}}

 Problem is that this.tile is null, until moveTo() is called.  If moveTo()
 has not been called, this.tile is null, and when destroy() is called we
 get an error.

 Fix is simple:

 {{{
    destroy: function() {
       if (this.tile != null)
          this.tile.destroy();
       this.tile = null;
       OpenLayers.Layer.prototype.destroy.apply(this, arguments);
    },
 }}}
