How do I switch an img when the user clicks it? : <p>I'm using wordpress. I've turned an image that I made into a button, and when the user CLICKS it, I want the image to change to another image of the same size, but a different color. Does anyone have a simple way of doing this?</p>

<p>Can I do everything in the "text field" of my page builder also... or do I need to also have some code in the background in my CSS editor.</p>

<p>Thanks :).</p>
