To align objects or images, first you need to have "Edit Page" selected across the top of the screen and make sure you are on the spread you wish to edit.
Then select two or more items or images. To select multiple images on Windows hold the control key while clicking items. To select multiple items on a Mac hold the command key while clicking items.
Once these images are selected, a black bar will appear beneath the images. The icon at the far left of the bar will allow you to align the selected images to the right, left or center.
