How can we drape a simple jpeg image which doesnot have any geo referencing information over the digital elevation model in order to visualize it in 3D in QGIS?

QGIS now has a very impressive rendering engine which you can use to drape one image over another. For example you can get a nice "3D effect" by draping an ortho-photo over a hillshade raster. You set the rendering in the first raster's Layer Properties page on the "Style" tab. There are several kinds of rendering, the "Darken" or "Multiply" options gives an excellent 3D effect.

To use this rendering you'll need to do two steps in advance: first geo-reference your jpeg image, and second, use your digital elevation model to create a hillshade raster. Both of these procedures are in the Raster menu in QGIS.
