Sure, just add the below line in red to your images array:
Code:
var myvacation=new Array()
myvacation[0]=["../photo1.jpg", "", "photo1-large.jpg"]
myvacation[1]=["photo2.jpg", "Our car", ""]
myvacation[2]=["photo3.jpg", "Our dog", "photo3-large.jpg"]
myvacation[3]=["photo4.jpg", "Our hotel", "http://www.gohawaii.com/"]
myvacation[4]=["photo5.jpg", "Our Computer", "http://www.google.com", "_new"]
myvacation[5]=["photo6.jpg", "Our house", "photo6-large.jpg"]
myvacation[6]=["photo7.jpg", "Our Friends", "http://www.ask.com"]
myvacation.reverse()
This reverses the contents of the array before passing it into the script.
