Greg,

One way to  set the button icons programmatically is to run  the 
"setUp" handler below. It presumes that each button which  is  to 
receive an image icon has been given the same name as the  image in 
the substack. It will run through all the cards in the main stack and 
if it finds a button whose name corresponds to an image in the 
substack, it will assign the image id to the button. (All images are 
located on the one card in the substack. It is relatively quick and 
painless.

On setUp
Lock screen
   repeat with i =1 to the number of cards
     set the defaultstack to "myStack"
     go to card i
     repeat with j = 1 to the number of buttons
       put the short name of button j into tButtonName
       set the defaultstack to "mySubstack"
       if there is an image tButtonName then put the id of image 
tButtonName into tImageID
       set the defaultstack to "images"
       set the icon of button j to tImageID
     end repeat
   end repeat
   unlock screen
end setUp
