By mistake I chose a huge file as my desktop picture but when I went back to change it System Preferences repeatedly quit when I got to the desktop picture window. I finally managed to change it theoretically by clicking on one of the system images before Sys Prefs quit but the old, huge picture is still there. I have restarted several times, updated my system software, corrected permissions and the picture is still there. I even moved the image to another location but no luck.
What preference file do I trash to get rid of this thing? What else will get trashed at the same time? I looked through my preference files but I couldn't pick out which one would definitely be it so before I cause more mayhem I thought I'd ask you guys.
Thanks.
