I have my screensaver set to show a slideshow of my iPhoto library, and when I got out of the shower this morning, I noticed a very strange thing.... There was a blue, pixelated, Indian totem pole-like face on my screen. Then, it proceeded to the next slide which was one of my pictures - nothing abnormal. But then again on the next slide, it was another pixelated Indian-like face, this time it was red with orange/yellow hair. The images of the faces were full-screened overtop of my regular images, and were very pixelated. A quite freaky surprise for me to see, to say the least. I have never seen these images before, and had no idea they were even on my computer. They are definitely NOT in my iPhoto library. Anyone ever notice this, and what/why/how does it happen?? A search shows me that I am not alone: http://forums.macrumors.com/showthread.php?t=142110 but no solution or reason was found.
