I just turned on my iMac (24-inch, Early 2009) and a new desktop image appeared. I did not choose that image. I did not do an update recently?
Would someone float some ideas about this?

It may be because your desktop image was in iPhoto and can no longer be accessed after a conversion to Photos -- although that shouldn't be the case unless you deleted your iPhoto Library. At any rate you may be able to go to Apple Menu > System Preferences > Desktop & Screensaver and find the original and set it back to that.
Why do I have a home screen image that I did not choose?
