I often use the graphics png format for diagrams maps etc, because it will produce smaller files and better quality for the viewer. The png format is also used very much on internet as the jpg format is. So every computer used on internet needs to be able to show such graphics. I suppose this should not cause any problems to use the png-format here - am I right? You can easily upload the png-format graphics.
