Hello, so I have the same image as the initial image before my Lock Screen Slideshow begins.

Initial Image:
Click image for larger version.

Then the Slideshow begins a few moments later:
Click image for larger version.

Is there an option that I can enable to set that Initial Image to be a random image from the slideshow images folder that I have? If not, is there some 3rd party application that can do that instead?

Thanks
