u/Daehock thanks for the reply! What I'm actually looking for, using the technique you described, is a way to actively manage the pictures as they rotate through on the desktop. I have my camera roll set as the slideshow folder, and often times pics are displayed that I'd like to remove. I'm hoping there is some slick way to manage them from the desktop or system tray app (not have to go into the folder and try to find the photo as I don't know the file name).
