Hi Mr. Sriranga, I think maybe because his files are JPEG the conversion to BMP produced a low quality file. Perhaps if you use a manual conversion -- not copy and paste -- it will produce different results? I'm pretty sure the dark line at the bottom and the lack of border / margins are the problem, along with perhaps the dark gray background color. --Sven
