You are getting an HTTP 400  Bad Request  error because there is a space in your URL  If you fix it  before the zoom parameter   you will get an HTTP 400 error  Unauthorized   Maybe you need some HTTP header to identify your download as a recognised browser  use the  User-Agent  header  or additional authentication parameter   For the User-Agent example  then use the ImageIO read InputStream  using the connection inputstream   URLConnection connection   url openConnection    connection setRequestProperty  User-Agent    xxxxxx      Use whatever needed for xxxxxx

You can try the this class to displays an image read from a URL within a JFrame   public class ShowImageFromURL        public static void show String urlLocation            Image image   null          try               URL url   new URL urlLocation               URLConnection conn   url openConnection                conn setRequestProperty  User-Agent    Mozilla 5 0                 conn connect                InputStream urlStream   conn getInputStream                image   ImageIO read urlStream                JFrame frame   new JFrame                JLabel lblimage   new JLabel new ImageIcon image                frame getContentPane   add lblimage  BorderLayout CENTER               frame setSize image getWidth null    50  image getHeight null    50               frame setVisible true              catch  IOException e                System out println  Something went wrong  sorry     e toString                 e printStackTrace                        Ref   https   gist github com aslamanver 92af3ac67406cfd116b7e4e177156926

Directly calling a URL to get an image may concern with major security issues  You need to ensure that you have sufficient rights to access that resource  However You can use ByteOutputStream to read image file  This is an example  Its just an example  you need to do necessary changes as per your requirement    ByteArrayOutputStream bis   new ByteArrayOutputStream    InputStream is   null  try     is   url openStream       byte   bytebuff   new byte 4096      int n     while    n   is read bytebuff    gt  0         bis write bytebuff  0  n

Try  public class ImageComponent extends JComponent     private final BufferedImage img     public ImageComponent URL url  throws IOException       img   ImageIO read url       setPreferredSize new Dimension img getWidth    img getHeight               Override   protected void paintComponent Graphics g        super paintComponent g       g drawImage img  0  0  img getWidth    img getHeight    this          public static void main String   args  throws Exception       final URL kitten   new URL  quot https   placekitten com g 200 300 quot         final ImageComponent image   new ImageComponent kitten        JFrame frame   new JFrame  quot Test quot        frame add new JScrollPane image         frame setDefaultCloseOperation JFrame EXIT ON CLOSE       frame setSize 400  300       frame setVisible true

This code worked fine for me    import java io FileOutputStream   import java io IOException   import java io InputStream   import java io OutputStream   import java net URL   public class SaveImageFromUrl    public static void main String   args  throws Exception       String imageUrl    http   www avajava com images avajavalogo jpg       String destinationFile    image jpg        saveImage imageUrl  destinationFile      public static void saveImage String imageUrl  String destinationFile  throws IOException       URL url   new URL imageUrl       InputStream is   url openStream        OutputStream os   new FileOutputStream destinationFile        byte   b   new byte 2048       int length       while   length   is read b      -1            os write b  0  length              is close        os close
