Photoslideshow + crossfade + preload

Hi Kirupians,
Sorry to bring up another slideshow questions, knowing how much you all love them :wink:
I used this:

… with a little change (chrossfading images) and I added 2 buttons (stop and play).
The stop works with the clearInterval, yet … the slideshow does not want to restart.
After 3 days (which is more than sad), I still can’t figure out why :puzzled: … Please anyone help.
Thanx in advance.
