[OpenLayers-Users] need Static image as map of small city with correct longitude and latitude

[Pierre GIRAUD]

You're not adding the layer to the map.

Try the following :

        function init(){
            map = new OpenLayers.Map('map');
            var options = { numZoomLevels: 5 };
            var olbound = new OpenLayers.Bounds(15.865164, 58.172783,
16.651403, 58.620233);           //bounds(left,buttom,right,top)

            var topography = new OpenLayers.Layer.Image(
                'Wrap signals',
                'img/image.24.png',
                olbound,
                new OpenLayers.Size(1000, 1000),
//size in pixel of the map
                options
            );
            map.addLayer(topography);
            map.zoomToMaxExtent();
        }

map.setCenter(new OpenLayers.LonLat(16.23069, 58.406794), 3);
