Anyone know of an on-line tutorial which will show me how to do this?

I need to be able to hit a button which will randomly throw up one of a set of pictures which depict a sport to the stage.

Then another button which will randomly pull up one of another set of pictures which will depict an opinion of that sport. e.g. Dislike/Love/OK etc

Do I need something to do with Arrays? Can you store images in an Array??

I understand buttons and how to create objects etc.
