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);
