Hi Eric,
BufferedImage questions are always welcome on the Java2D list.
You might have better luck getting the ColorModel, asking it to
create you a compatible raster, and then using the BufferedImage
constructor that takes a ColorModel and a Raster.
But, if the original image was a GIF then the image returned from
ImageIO would be an indexed image and you might not want to have
a compatible image for the reduced version as that would involve
some dithering - so perhaps it isn't always the best solution to
request an image in the same format as the original.
In this particular case, I'm guessing that you weren't working with
a GIF since reading a GIF would not tend to return a CUSTOM image...
