I've just installed Wallch, and it's working wonderfully. I have set the program to cycle a huge number of images all within a folder on my computer. There are so many images that I've forgotten about many of the ones popping up! I'm like to look into what they are.

Is there any way to tell which image is currently my background? I'd expect the answer to be in some linux code I' unfamiliar with, or a hidden feature of Wallch.

I found nothing in the Wallch GUI nor the Appearance settings. I'm running Ubuntu 12.4 and Wallch 3.0.
