Xml and dynamic sequencing

hi there, i got a xml driven gallery. i just read nodes and print em on screen with a simple “for… next” loop. im just wondering, how can i sequence the load progress. i mean 1st thumb shows up, and then, lets say 1 second delay time… then load 2nd thumb … then 3rd… so on… i dont want em to come up all at the same time, just need a little sequence. hope you understand the situation (:

thank you.
