[edit] Solar chimney

If its possible please make a png-Version of the original "Solarchimney" image. Using jpg as format for graphics makes the picture bigger than needed and some ugly colors (at the border) are caused by the compression. Png saves continious areas with one color. In general png is better for graphics, while jpg is preferred for photographs and pictures with a lot colors and small areas. There's a lot more to say, but I hope you can see why a png-Version would be better. Thanks and greetings, Amtiss, SNAFU ? 18:03, 23 July 2006 (UTC)
