What I meant was when you are in the main splat interface and go to the theme selector I was getting a blank preview of the theme because I assumed incorrectly that when you saved a modified theme that the software created a preview image for you. I didn't realize you had to create it yourself.
Exactly, you have to select an image to display as the preview in the Theme Editor properties. Otherwise, it displays nothing, just a blank image. That's also where you give a description of your theme and fill in who the author is.
