After reading around in the forum and not finding a similar

After reading around in the forum and not finding a similar situation, I figured I would ask. All of a sudden when I am adding images to the background they don't seem to be loading when the site renders (though they are showing in the upfront interface, and initially they were rendering just fine).

Parallax or fixed, neither seem to be making their way to the actual site.

Again, they started out loading on the page, and now they don't seem to want to load on the page but show in the upfront WIZIWIG.
