use a Base64 decoder to convert the string to binary, and create your image from that.

Image image = Toolkit.geDefaultToolkit().createImage(new sun.misc.BASE64Decoder().decodeBuffer(stringToDecode)));

Try this:

byte[] imageBytes = new sun.misc.BASE64Decoder().decodeBuffer(stringToDecode);
BufferedImage bi = javax.imageio.ImageIO.read(new ByteArrayInputStream(imageBytes));
javax.imageio.ImageIO.write(bi, "jpg", new File("my.jpg"));
