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?

Try the GDAL tools plugin. You could try georeferencing your image, it would probably be as a tile that might be a targa image, conversions you may be able to make in photoshop, If you just want a visual or a VRML out, viewable in a browser display with vrml viewer extensions installed you can try "http://www.hangsim.com/3dem/" 3DEM freeware on XP

You can use GRASS GIS for it (perhaps even via GRASS toolbox of Sextante in QGIS), it offers 3D visualization through its nviz module. For examples, see: http://grass.osgeo.org/screenshots/3D (e.g., Perspective Landsat TM RGB visualization).
