Actually, I believe that JPEG encodes the DPI. At least Photoshop thinks so - I haven't read the JPEG spec to be sure. However - I am not aware of any browser that actually reads the DPI and Photoshop does it nearly invisibly to the user - which frequently results in images being saved with some absurd resolution like 300 DPI indicated if you are not paying attention. -- Benjamin Franz
