I like to use my wallpaper as console background image, and I like to use slideshow for my wallpaper. Not every wallpaper is an appropriate background for text though and so the tint color option is handy, but a lot of my wallpapers have nighttime versions and it looks really cool to use those instead of tinting. Here's a couple of examples:

..and so I'm thinking a feature where ConsoleZ can select the background version for the current wallpaper. It could be as simple as allowing a placeholder like %currentwallpaper% in the background image path or some simple pattern for specifying the folder naming convention.
