Visual Basic ComboBox Help!

I'm making a program in visual basic and need some help with some code.

Ok, I have a combo box named "cboComputer" and some images named "imgPowerful "and "imgExtreme ".
In the list of the combo box I have "Powerful" and "Extreme ".

Now when I run my program I want one of the images to appear when the user clickes on one of the items in the combobox. An example would be if a user clicked on the "Powerful" item in the box then the "imgPowerful" should appear on screen.

I hope someone can help me out or point me to a real good web site that might have something on it that can help me.
Thanks in advanced.

 

Maybe better luck here than in the Discussions section.
