Use "preopencard" that will happen BEFORE a card is drawn on the screen,
see below...

Let me see if I get you right:

You want to hide every image on every card before you go to that card?
And have this in the stackscript?

In that case put this "preopencard" handler into the stackscript!

on preopencard
   repeat with i = 1 to the num of imgs
     hide img i
   end repeat
end preopencard

"hide" is immediate, but "wait" will halt the application for the  
time you wait,
means you cannot click buttons etc. in this time.

But you can force the "wait" clause to NOT halt the whole app by adding:

on openCard
    wait 2 secs WITH MESSAGES
    hide image "img1"
end openCard

Now you can enter text into fields, click buttons etc... during these  
2 seconds.

See above...

Hope that helps...
