The built-in Photos app in Windows 8 has a live tile on the start screen that shows photos from your pictures library. It's a cool little visual, even if it's not particularly useful.

The problem is that a lot of image files on my computer are not really photos per se -- I have a lot of screenshots, PNGs of technical drawings, graph images, etc. Those all look pretty awkward on the start screen. I look pretty awkward on the start screen too... sometimes photos like resume profile shots show up that I don't want to delete, but they're not really what I want to be staring at when I start my computer up.

I'm looking for some way to configure which folders the Photos app should look in for images to display on the live tile. That way, I could point it to some directories of pretty scenic pictures I've taken, and not have to see graphs and my own mug.

For the time being, I've just disabled the live tile (right click -> disable live tile), but I would ultimately like to have this functionality, just with more control over it.
