[Gambas-user] how to create buttons with array

[Francesco Xavier Kolly Mally]

hello everybody,
my name francesco and I have problem with array, this is the situation:
1. I have a form and one picture named pic.png and a button
2. If I click the button and pic.png will appear in form and if I clik again
the button then pic.png will appear again so now I have 2 pictures(pic.png)
and so on.
3. now, the question it's "what is the syntaxe for my problem???"

Thank you
