If you are using Java 2D, you can create a JPEG image by using  the
com.sun.image.codec.jpeg package. The code below creates a JPEG image and
saves it to a file.

   public void save(BufferedImage destImage, String filename) {
      try {
         ByteArrayOutputStream boutstream = new ByteArrayOutputStream();
         JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder(boutstream);
         enc.encode(destImage);
         FileOutputStream fimage = new FileOutputStream(new File(filename));
         boutstream.writeTo(fimage);
         fimage.close();
       } catch (Exception e) { }
    }

The code snippet below shows how to crerate a BufferedImage:
       BufferedImage bi = new BufferedImage((int)imWid,
                                            (int)(imHt),
                                             BufferedImage.TYPE_INT_RGB);
       Graphics2D g2d = bi.createGraphics();

       g2d.drawImage(img, dispTx,this);

                     img : Your image object.
                     dispTx: The Affine Transform.
                     You can use other drawImage()methods for drawing images.

     Once the image is drawn, you can save it using the save() method.

I am not sure what you mean by combination of images. If it means creating a
single image from a combination of images layed in a grid ( row X column)
fashion, you can use the following code snippet from my Java Image Browser
(http://www.execpc.com/~larryhr/ib.html). If it is in a single row, modify the
code appropriately.

    public void createSingleImage() {
       Dimension dim = getCellSize();
       int imWid = cols*dim.width;
       int imHt =  rows*dim.height;
       BufferedImage bi = new BufferedImage((int)imWid,
                                            (int)(imHt),
                                             BufferedImage.TYPE_INT_RGB);
       Graphics2D g2d = bi.createGraphics();
       int x = 0; int y=0;
       for(int i=0; i< rows; i++) {
           for(int j=0;j<cols; j++) {
               if(i*cols+j >= imageset.length) break;
               Image img = imageset[i*cols+j];
               if(img != null)
                  g2d.drawImage(img, x+1,y+1, dim.width-2, dim.height-2,this);
               x += dim.width;
           }
           x =0;
           y += dim.height;
        }
       save(bi);//calls save(BufferedImage, filename) after getting the
filename.
    }
imageset is an array of preloaded Image objects.
