	.bmp are not medium quality they are lossless. .png is a compressed version of .bmp .bmp monochrome is black and white only. Also lossy formats will deteriorate with each save and load cycle. You might want to mention that too. You can find more information here: http://en.wikipedia.org/wiki/Image_file_formats#PNG Edited by Pixel_Outlaw - 23 February 2008 at 1:41pm

	They do not lose any of the original quality. They stay the same, so they would be high quality.

	"Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. This can be contrasted to lossy data compression, which does not allow the exact original data to be reconstructed from the compressed data." http://en.wikipedia.org/wiki/Lossless also, Ii would put more emphasis on a description about how does saving in each format affects people's works, rather than giving a generical tech info of each format. the image does not really work as an ilustration of the explanation.
