Something a little different

I found a tool to take Images from my screen and thought I'd show you my desktop at present. It's Jammers modeling again for the camera. Something else different is that this is a Bitmap image compared to all of the other Images which are of a JPEG format. I have been told there is a big difference in the quality of the shot. I guess I need to see for myself.(Of course this is a bitmap of an original JPEG capture)
