I'm not really sure what you question is but if you have a BufferedImage then you simply create an ImageIcon using the image, then you add the icon to a JLabel and add the label to the GUI like any other component.

  • This just makes the smallest window possible.
  • It's been a long time since I used swing, but i'd guess you didn't call pack() if you have a tiny window
  • exactly what i was looking for, quickly check whether bufferedImages are read correctly .. no need for all this JComponent extending and print overriding. Thanks!
  • @IanWill you will also need to call frame.setPreferredSize(new java.awt.Dimension(int width, int height)); before calling frame.pack(); importing java.awt.Dimension also works too :) Also this should be the selected answer. +1 for code example.
