How do I replace the background in the Band Demo?

The background has animation between two different versions of the same wallpaper, red and blue. I can’t seem to replace the background. No matter what I do, unless I delete both files, it’ll show up. Please let me know as soon as possible.

NVM, figured it out. had to scroll down on the default edit page, not cornerstone, to add and remove images.

Hi There,

Glad you sorted things out, you can actually access those settings inside the Cornerstone. It is under Settings > X Settings > Background Image(s)
