You can find some examples how to do it in the setup classes. Here is a code 
snipped how you can do it:

        Obj obj= new Obj();
        MeshComponent imageMesh = GLFactory.getInstance().newTexturedSquare(
                "uniqueImageId",
                IO.loadBitmapFromId(myTargetActivity, R.drawable.icon));
        imageMesh.addAnimation(new AnimationFaceToCamera(camera, 0.5f));
        obj.setComp(imageMesh);

The addAnimation(..) stuff is useful if you want the image to always face the 
camera

The camera you need is a GLCamera and you have to create it on your own if you 
are using the normal Setup class. If you are using the DefaultARSetup class you 
can get the camera object by calling getCamera() inside your setup class. The 
best thing would be to take a look at the implementation of DefaultARSetup. The 
camera is needed when a new World object is created and you need it every time 
when the position in the virtual world (like facing a mesh to the user) is 
relevant.
