Picture with Select Option

I have a select control with 3 options. I would like to display 3 individual pictures on 3 different options. And I would like to get the pictures in the middle of the page. Using PHP how can I cope up the situation. I am in a hurry. Please do the needful.

This is an HTML issue. You should post in the HTML forum. But when you do, explain in more detail what you're trying to do, because I for one have no clue what you mean.
