In Windows, open the folder containing your images and select the files.
Drag the files to the tracing window.
Select a loading option:
Load all into a grid layout: Loads the images to create a single plane montage.
Load individually: Use this option if you need to set scaling for each image.
Load all into one stack: Loads all the images into one image stack.
The Image Scaling and Placement dialog box opens if 1) scaling information is not embedded in the image file, 2) you selected Load individually; make the necessary adjustments.
Click OK.
If you load an image for which there is no matching lens, you will be prompted to create a new lens to match the image scaling. See Creating a lens for help.
