Question

There is no specialized image component provided in Swing  which is sad in my opinion   So  there are a few options    As  Reimeus said  Use a JLabel with an icon  Create in the window builder a JPanel  that will represent the location of the image  Then add your own custom image component to the JPanel using a few lines of code you will never have to change  They should look like this   JImageComponent ic   new JImageComponent myImageGoesHere   imagePanel add ic     where JImageComponent is a self created class that extends JComponent that overrides the paintComponent   method to draw the image

As martijn-courteaux said  create a custom component it s the better option  In C  exists a component called PictureBox and I tried to create this component for Java  here is the code   import java awt Dimension  import java awt Graphics  import java awt Image  import javax swing Icon  import javax swing ImageIcon  import javax swing JComponent   public class JPictureBox extends JComponent        private Icon icon   null      private final Dimension dimension   new Dimension 100  100       private Image image   null      private ImageIcon ii   null      private SizeMode sizeMode   SizeMode STRETCH      private int newHeight  newWidth  originalHeight  originalWidth       public JPictureBox             JPictureBox this setPreferredSize dimension           JPictureBox this setOpaque false           JPictureBox this setSizeMode SizeMode STRETCH               Override     public void paintComponent Graphics g            if  ii    null                switch  getSizeMode                      case NORMAL                      g drawImage image  0  0  ii getIconWidth    ii getIconHeight    null                       break                  case ZOOM                      aspectRatio                        g drawImage image  0  0  newWidth  newHeight  null                       break                  case STRETCH                      g drawImage image  0  0  this getWidth    this getHeight    null                       break                  case CENTER                      g drawImage image   int   this getWidth     2  -  int   ii getIconWidth     2    int   this getHeight     2  -  int   ii getIconHeight     2   ii getIconWidth    ii getIconHeight    null                       break                  default                      g drawImage image  0  0  this getWidth    this getHeight    null                                      public Icon getIcon             return icon             public void setIcon Icon icon            this icon   icon          ii    ImageIcon  icon          image   ii getImage            originalHeight   ii getIconHeight            originalWidth   ii getIconWidth               public SizeMode getSizeMode             return sizeMode             public void setSizeMode SizeMode sizeMode            this sizeMode   sizeMode             public enum SizeMode           NORMAL          STRETCH          CENTER          ZOOM            private void aspectRatio             if  ii    null                newHeight   this getHeight                newWidth    originalWidth   newHeight    originalHeight                       If you want to add an image  choose the JPictureBox  after that go to Properties and find  icon  property and select an image  If you want to change the sizeMode property then choose the JPictureBox  after that go to Properties and find  sizeMode  property  you can choose some values    NORMAL value  the image is positioned in the upper-left corner of the JPictureBox  STRETCH value causes the image to stretch or shrink to fit the JPictureBox  ZOOM value causes the image to be stretched or shrunk to fit the JPictureBox  however  the aspect ratio in the original is maintained  CENTER value causes the image to be centered in the client area     If you want to learn more about this topic  you can check this video   Also you can see the code on Gitlab or Github
