Try this code
ArrayList<Bitmap> mBit = new ArrayList<Bitmap>(9);
for (int i = 0; i < 9; i++)
{
mBit.add(Bitmap.createBitmap(bitmapOrg, (i % 3) * newWidth, (i / 3) * newHeight, newWidth, newHeight));
}
Collections.shuffle(mBit);
for (int i = 0; i < 10; i++)
{
Bitmap bitmap = mBit.get(i));
//Do something here
}

try adding a basic explanation, it'll help them better understand it :).
You should create an ArrayList of objects and you can put everything you want in it and manipulate like this :
ArrayList<Object> array = new ArrayList<Object>();
array.put(0,"A string");
array.put(1,yourbitmap);
String string = (String) array.get(0);
Bitmap bitmap = (Bitmap) array.get(1);
You must cast when you get get because it is an object array.

If by image, you mean an image File and not Image object. Then use
add(fileObject.toString())
and while retrieving recreate File object using that object String.
new File(array.get(0)).getPath()
ArrayList<String>can only hold Strings. You can store, say, the path to the image as a string, or perhaps the image itself encoded in base64. Which are you trying to do? If it's the latter, make it an ArrayList<File> or ArrayList<Image>.
