The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

Support for BMP images wasn't added to ImageIO until Java 5.
You should be able to grab the sources for the GNU ImageIO BMP implementation, and use those with Java 1.4. That would still allow you to use ImageIO.
I wouldn't use JAI for image loading/saving; my impression is that it's been abandoned for the most part.
