Desktop Image Problem

[Phil Ex Machina]

Hey, everyone. I bought an iMac over the summer, and have had a slightly annoying issue. Hopegfully someone can help.

The process goes as follows:
I set my desktop image.
I log off/shutdown/restart the Mac.
My desktop image is now the image I had previously.

My Mac normally doesn't remember my desktop unless I leave it up for several weeks or so.

Any ideas?

Any help would be appreciated.

Go into your system prefs for your desktop, and see if the option is checked to automatically switch the background when you log out.

After that, I would run a permissions repair through Disk Utility and resetting the PRAM.
