Select a previous selected shape

How i can after i create a duplicate move back the selection to the orig shape.
So that this Original image always is selected?

In my case is it so:

i select a picture and create a duplicate on the right side. But after this is the duplicate selected. I would like that is only the origin Image is selected

            corelApp.ActiveSelection.Shapes.All().CreateSelection();
            xSize = corelApp.ActiveSelection.SizeWidth;
            origImg = corelApp.ActiveSelectionRange.FirstShape;
            origImg.Duplicate();
            corelApp.ActiveSelection.Move(xSize+3, 0);
            //ConvertImage();
        }
