Hi there, I have a really simple task that I need help on...

I want to have 4 images side by side.. they are all buttons.. when i click one of them it changes colour, and reveals text underneath.. If i click another one of the buttons the first button changes back to the original colour and the new button i have clicked changes colour and the text underneath is replaced with new text... seems simple right? Any tutorials or examples of what I'm looking for would be appreciated.

Thanks in advance.
