And to address your issue with perspective, here is a model of the CSM.
Note the attachement of the high gain antenna at the back of the service module. Now what hapens if we move closer?
Oh look, the cylindrical service module has disappeared, even though the conical command module is still pointing off to one side. You can see the service module is still attached because the high gain antenna is still clearly visible.
THis is basic perspective, tarkus, nothing unusual at all. The service module is still attached in your 'missing service module' pictures, you just can't see it because it is hidden by the command module from the perspective of the photographer.
