GetResourceAsStream problems Read(byte[])

Question

Heres my code. Some images show up fine, others dont show up at all, and others show up as black images when the images are in a jar file. All images show up fine when they are on the lcoal file system. All images DO fit in the ~60kb byte array. Any suggestions on what the problem is, I have worked around my problem but I would like to know what was going on. My work around was to loop inputstream.read() into the byte array and that has worked.
    public static ImageIcon GetImage(String fileName)
        InputStream iStream=null;
        ImageIcon ic = null;
        try
            if( classLoader == null )
                try
                    classLoader = Class.forName( "myappclass" ).getClassLoader();
                catch( Exception x)
                    System.out.println( x.toString() );
                    return ic;
            iStream = classLoader.getResourceAsStream( fileName );
            byte[] bytes = new byte[65000];
            iStream.read(bytes);
           //heres around where it goes caplooyey
            ic = new ImageIcon(bytes);
        catch (IOException ex)
//            iStream.close();
            System.out.println("No existing file to copy");
            return ic;
        return ic;
    }

Answer 1

Your code is reading the stream before all the data are available so one read will grab only a partial image. One solution would be to use a BufferedInputStream, but that would consume even more memory than your current approach.
A much simpler, more efficient, and wholly equivalent technique is accomplished with this one line of code:
ic = new ImageIcon(ClassLoader.getSystemResource(fileName));
