[OpenLayers-Users] Projection Problem

[Kusum]

Dear All

I have a world image which I want to show at orthographic projection so that it appears as a globe.
So I am using this image
var options = 
     {
            numZoomLevels: 10,
            projection:"EPSG:9840"
     }
layer = new OpenLayers.Layer.Image(
                                'World Map',
                                'http://localhost/maplab/app_atlas/images/wsiearth.GIF',
                                new OpenLayers.Bounds(-180,-47.48309659090924,180,90),
                                new OpenLayers.Size(580, 320),
                                options);


But it is shown as a flat image and not as globe.

I am using Mapserver .
Is there any code change I have to make to get the image in globe form.

Pls suggest.I am completely messed up.

regards
Kusum
