3 Notes

1. All the binary builds are available on http://download.java.net/media/jai-imageio/builds/release/1.1/
2. The jar files are required.
3. The dll/so files are optional.
4. The dll/so files provide acceleration for certain image types.
5. The dll/so files may also provide support for additional image types.
