Just posing a question I wanted other people's opinions on. How come nobody uses PNG? Png has lossless compression, that is completely reversible Open standard 48-bit and has alpha transparency Sure PNG files take up more room than JPG's, but less than Tiff. To me it sounds like an ideal way to store digital images these days, where storage off camera isn't in that short of a supply. Most people have broadband these days so loading images wouldn't be that bad. To learn more about PNG files, visit your local library or click http://www.libpng.org/pub/png/pngintro.html.
