Desktop wallpaper strangeness

This started two days ago. Whenever I boot up, my desktop wallpaper is gone, leaving a plain white background. I can reload it with minimal trouble, but it’s gone again when I shut down and boot back up. Why might this be?

Is it just plain white or is it that “error loading” message that’s there instead of your background that presents you with a refresh button?

It’s no longer an issue, having resolved itself in the wake of tons of other computer issues. Oh well.
