A Mystery!

I had my camera, as usual, yesterday at the Skagit Valley Tulip Festival and discovered after loading my photos on the computer that some (not all, thank goodness) of my photos were tiled like this one. I still haven't figured out what button(s) I must have accidentally pushed! But the festival was alive with vibrant tulip colors and many, many people - the traffic was really backed up! The weather cooperated!
