How to get an InputStream from a BufferedImage?

How can I get an InputStream from a BufferedImage object? I tried this but ImageIO.createImageInputStream() always returns NULL

BufferedImage bigImage = Grap

If you are trying to save the image to a file try:

ImageIO.write(thumb, "jpeg", new File(....));

If you just want at the bytes try doing the write call but pass it a ByteArrayOutputStream which you can then get the byte array out of and do with it what you want.
