Yes, the user agent should know the pixel density of the image. PNG *does* have a chunk named pHYs where you specify the image physical dimensions. Of course JPEG also stores information about density. I don't know about GIF, but I hate it anyway and its days are over. All images should have density information. The web browser should know the density of the intended display device (monitor, printer, etc.) and optimize the image for output at that density. This is the way to go, no comment. Iñigo López
