Customizing the Live Preview App to Show Round Swatches?

[wickedbride]

I'm using the Live Preview App by Webyze, and they were really helpful for some other issues I had, but I'm on my own for figuring out a snippet of custom code. I've gone around in circles and tried several things, but nothing worked - hoping someone here can help. I want the image swatches to display as small round swatches, like the block above the foils. Any assistance is appreciated - thanks!
