Randomly Sort array of integers

Question

All,
I have a question. I am writing an applet that loads a bunch of images into an array and then draws all the images in the array. However,I want to be able to randomly shuffle the images in the array and print them out.
I can randomly do this with numbers but how would I do it for a array of images?
Thanks

Here's something I use for shuffling object arrays: public class Shuffler {
    static private final Random RNG = new java.util.Random() ;
    static public void shuffleObjects(Object[] objs) {
        int offset = 0 ;
        int cnt = objs.length ;
        while (cnt > 1) {
            int swapIdx = RNG.nextInt(cnt) + offset ;
            if (swapIdx != offset) {
                Object tmp = objs[swapIdx] ;
                objs[swapIdx] = objs[offset] ;
                objs[offset] = tmp ;
            offset++ ;
            cnt-- ;
}
