I'm starting a new project using the "Holiday" theme. There are several pictures in the theme that are black and white and change to color on mouse over. I reviewed the tutorial that shows how to make this effect from scratch, however I wanted to know if there is a way to drag and drop pictures into the theme and get the same effect (black/white to color). When I drop my pic into the frame both the base layer and the pop-up layer are color. I tried to separate the layers but was unable to see where the pop-up/mouse over effect was created.
