Optical Illusions: Can You See Two Images In One Picture

I thought I was pretty good at these optical illusion things. A picture that contains two images. Here is a challenge for you. There are 12 pictures and you have to find both images in 15 seconds or less. Full disclosure I got 10 our of 12 right away. Picture number 6 was hard and took me more that 15 seconds but I found it as for number 5 still can't figure it out. Give it a try.- Sally
