Why JPEG? JPEG is not well suited to storing images
that are mostly text or line drawings. PNG might be
better suited (especially if you drop the image to 256
or less colors).

A good way to test is to write a class that uses
the functionality you are interested in, then
attempt to compile it using a -bootclasspath
pointing to a 1.3 version rt.jar.
(Note, you might also consult a late model JavaDocs
and look for the '@since' tags, but that is not neally
as certain as compiling aginst the 1.3 jar)
