Why does my desktop image change back?

[ndstrenge]

If I change my desktop image, it often changes back to its previous setting next time I boot up. And- it doesn't remain constant between graphics cards either. (15" late '08 UMBP)

It changes when I connect external monitors, and it changes when I bring it home from work and boot up.

I just can't wrap my head around it. I have to change it every time I boot up, actually.

My school MacBook sometimes does that! Have you changed the backround in the system preferences or another method? And where if the picture located that you want as your backround?

I go through system preferences and host the pic in an iPhoto folder.

Is this a SnowLeopard bug? Never had problems before SL.
