Re: Random backgrounds

read the filenames into a List, generate a sequence of random numbers, et voila.

Re: Random backgrounds

You should be able to defer the code from what I wrote.
It's simple really.

Java Syntax (Toggle Plain Text)
List map = new ArrayList();
// loop through files
while (files.hasNext()) {
  map.add(files.next());
}
List map = new ArrayList();
// loop through files
while (files.hasNext()) {
  map.add(files.next());
}

or something like that.
That's of course not complete code but should serve as a starting point

Re: Random backgrounds

Use a Random object or something:

Random random = new Random(2);

int rotation = random.nextInt()+1;
