pointing to a web image

Jan 13, 2014 at 11:44 PM
Shouldn't I be able to just change one of the "ms-appx///images/photo.png" strings to a web image location?

I changed one of the strings to an image I have on my website but it's not showing up in the live tile. So I wanted to check with you to see if this is what I change, in order to know if I'm editing the string incorrectly or if I just don't have the web image URI typed correctly.
