Imported image sequence too big

I have 155 images that are 900 pixels x 1220 pixels in size. These images make up an animation. when I import them to Pencil 2D, the image(s) is/are larger than the work space in Pencil 2D. Is there a way to make the work space larger or simultaneously reduce the images to fit the work space?

Double click on the camera layer on the timeline at the bottom and a dialog will popup to allow you to change the camera (work space) dimensions to match that of your images.
