Here are a few tricks to help you in managing your stacks. The first photo you select when creating a stack (the top photo) will remain visible when the stack is collapsed. If that’s not the photo you want to represent your stack, you can make any photo in the stack the top photo. First, expand the stack. Then Control-click (PC: right-click) directly on the photo you want at the top of the stack. When the pop-up menu appears, choose Stacking > Move to Top of Stack (see Figure 6).
