image paste

[Andrew]

Thanks for all those that responded to my questions about images and 
animation.  Your suggestions were very helpful.
Meanwhile, I'm having a basic little problem.
When I paste an image on a card (again, its rect appears as big as the 
whole card, no matter the size of the image), and then I paste a second 
image on the same card, the second image seems to become part of the 
first one.  What can I do to make the two images separate objects?
Thanks! :)
