helpdid you read the examples in JFilechooser Tutorial?
all you have to do is modify to it.
here's the code:
ImageFilter Class
import java.io.File;
import javax.swing.*;
import javax.swing.filechooser.*;
public class ImageFilter extends FileFilter {
    //Accept all directories and all gif, jpg, tiff, or png files.
    public boolean accept(File f) {
        if (f.isDirectory()) {
            return true;
        String extension = Utils.getExtension(f);
        if (extension != null) {
            if (extension.equals(Utils.tiff) ||
                extension.equals(Utils.tif) ||
                extension.equals(Utils.gif) ||
                extension.equals(Utils.jpeg) ||
                extension.equals(Utils.jpg) ||
                extension.equals(Utils.png)) {
                    return true;
            } else {
                return false;
        return false;
    //The description of this filter
    public String getDescription() {
        return "Just Images";
}Utils Class
import java.io.File;
import javax.swing.ImageIcon;
/* Utils.java is used by FileChooserDemo2.java. */
public class Utils {
    public final static String jpeg = "jpeg";
    public final static String jpg = "jpg";
    public final static String gif = "gif";
    public final static String tiff = "tiff";
    public final static String tif = "tif";
    public final static String png = "png";
     * Get the extension of a file.
    public static String getExtension(File f) {
        String ext = null;
        String s = f.getName();
        int i = s.lastIndexOf('.');
        if (i > 0 &&  i < s.length() - 1) {
            ext = s.substring(i+1).toLowerCase();
        return ext;
    /** Returns an ImageIcon, or null if the path was invalid. */
    protected static ImageIcon createImageIcon(String path) {
        java.net.URL imgURL = Utils.class.getResource(path);
        if (imgURL != null) {
            return new ImageIcon(imgURL);
        } else {
            System.err.println("Couldn't find file: " + path);
            return null;
}
