Certain page designs require uniform sizes for multiple pictures on a page. This is easily accomplished in a three-step process: First define an aspect ratio, then define a cut-out area, and finally scale the images to the required size.
Select all images requiring the same size.
Select Image Toolbox from the Edit menu.
Open the Crop tool and enter the desired pixel dimensions. Select the “Fix” option to lock the aspect ratio.
Press the Copy button to apply the same pixel ratio to all pictures in the selection.
With the Fix option selected, enlarge, reduce or move the cut-out area of the first pictures.
Use the picture arrow buttons to access the other pictures in the selection and enlarge, reduce or move the cut-out area for each of the other pictures as necessary.
Open the Scale (Absolute) dialog, enter the required image dimensions.
Press the Copy button to scale all images to the same physical dimensions.
