Chapter 9 Stacking Images and Making Picks 109
Arranging Images in a Stack
It can sometimes be difficult to decide which image in the stack should be the pick. In
many cases, images are so similar that more than one of them merit the pick position.
For this reason, you may want to have alternate images available when presenting
images to clients. The image next to the pick is the “alternate.”
You can change the order of images within a stack to help you choose the pick and an
alternate. Moving an image to the left promotes it, and moving an image to the right
demotes it.
To promote an image in a stack, do one of the following:
m Select an image, then choose Stacks > Promote, or press Command–left bracket ([).
m Drag the image over the image location you want until you see a green bar appear,
then release the mouse button.
To demote an image in a stack, do one of the following:
m Select an image, then choose Stacks > Demote, or press Command–right bracket (]).
m Drag the image over the image location you want until you see a green bar appear,
then release the mouse button.
Adding Images to and Removing Images from Stacks
You can add images to and remove images from stacks at any time. You can drag
images in or out of a stack, as well as drag images from one stack to another.
To add an image to a stack:
m Drag the image into an expanded stack.
To remove an image from a stack, do one of the following:
m Select the image, then choose Stacks > Extract Item (or press Shift-Option-K).
m Drag the image out of an expanded stack.
