import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;


class ImageRenderer extends DefaultTableCellRenderer {
      JLabel lbl = new JLabel();
      public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        lbl.setIcon((ImageIcon)value);
        return lbl;

      }
    }

and

ImageIcon icon = new ImageIcon("myicon.png");
tabla.setValueAt(icon, 0, 7);
jTable1.getColumn("Link").setCellRenderer(new ImageRenderer());

Answer 1

and easiest for coding is implementations of prepareRenderer, for example

notice prepare all Graphics Objects before as local variable, don't, never load Graphics from File, Stream not from JDBC, becuse XxxRenderer can fired its events on every, mouse, and keys events
