Im going to try to explain myself better!

Example:
I have 2 buttons, and 100 images that i want to appear in the background each time one clik appens.
When i release b1 - a random object is added to the background.
If i release b1 again - another object is added
If i release b2 - another object is added
....... and it goes on and on - till i have no more objects to fill the background

Another thing - Im using MX -

Thanks again - hope you have understood my quest now
