The first thing you really need to do is set up a template card with 
your textField; perhaps
with a button next to it with the following type of script in it:

on mouseUp
   if the visible of field "TWEET" is true then
     set the visible of field "TWEET" to false
   else
     set the visible of field "TWEET" to true
   end if
end mouseUp

and a pair of navigation buttons to trot back and forth between your cards.

You can then duplicate the template as many times as you like: 
Edit/Duplicate Card
(this ONLY works when you have the Object Inspector open for the card).

Hyuck, hyuck, hyuck. The difference between Livecode and "yer 
bog-standard flashcard thingy"
is VAST; Livecode is a full-blown programming language.

If you import a folder of images onto a card: File/Import As Control/All 
Images In Folder . . .

select them all: Edit/Select All

then select Object Inspector: Object/Object Inspector

then look at Align Objects: Distribute/Edge To Edge

then Group them: Object/Group Selected

then look at Size & Position in the Object Inspector and CENTRE your group,

set the group's width & height to what you want,

then look at Basic properties in the Object Inspector and select the 
Horizontal scrollbar.

At this point you should have a number of pictures of tweety-birds in a 
group such that you
can only see one picture at a time, and you can scroll left & right 
between them.

> I made a scrolling group, pasted multiple pictures in it. That works on one card. But if I set bgBehavior to "true," then "new card" duplicates all the pictures, and the pictures are shared between cards. I want different pictures on each card. If I set bgBehavior to "false," making a new card becomes complicated.

Sadly, I have a feeling you will have to do this manually; or go a 
totally different route . . .

call your template card "TWEETY" via the Obj. Inspector.

Your template should NOT contain any images.

So; let's have a button on the template card called "DO IT BABY" with 
the following sort
of script:

on mouseUp
  clone card "TWEETY"
  set the name of card "TWEETY" to "TWEETY2"
--obviously this is a bit daft, you could have a field that counts the 
cards and assigns them numbers as they are cloned---

{this is where you can have your import routine}

select all

--this is where I get stuck as I cannot, for the life of me find out the 
language equivalents of
the alignment commands in the Obj. Inspector--

group the selected
call it "BLUETIT"
move group "BLUETIT" to 400,400 --always supposing your stack is 800,800--
set the width of group "BLUETIT" to 700
set the height of group "BLUETIT" to 600
set the hScrollbar of field "BLUETIT" to true

end mouseUp

Sorry; I have a feeling all this will do is make you reach for the aspirin.
