Trying to use "for" loop for slideshow

1

Hi,
I am trying to publish a slide show and loved your tutorial online to help- but I want the slideshow to automatically sequence thru pictures and I am trying to use a “for” loop but I don’t think I am placing the code very well. Could you help?

this is what I have for the “for” loop- but not sure how to place it

//for loop to sequence thru pics
for(i=0; i<this.pArray.length; i++) {
this.changePhoto(i);
};

thanks for you help. Blythe
