You draw the image on an offscreen canvas which you create on the server side (program which uses ServerSocket), use pixelgrabber class to get the bytes of the image, send the image to applet. In the applet side, use MemoryImageSource to construct back the Image from array of bytes and display the image where ever you want.

You can also read the jpeg image file as byte stream, send it to the applet, applet uses Toolkit.getDefaultToolkit().createImage(byte[] imagedata) method to create the Image back and display

The createImage method understands the byte array format to be either gif or jpeg and handles appropriately
