1. A computer-implemented method comprising: storing a threshold time value; automatically arranging a set of digital images into a plurality of stacks based on the threshold time value; and causing display of a graphical representation of each of the plurality of stacks; wherein automatically arranging includes: comparing a creation date and time associated with a first digital image from a set of digital images with a creation date and time associated with a second digital image from the set of digital images to determine a first difference value that reflects a difference between the creation date and time associated with the first digital image and the creation date and time associated with the second digital image; comparing the creation date and time associated with the second digital image with a creation date and time associated with a third digital image from the set of digital images to determine a second difference value that reflects a difference between the creation date and time associated with the second digital image and the creation date and time associated with the third digital image; in response to determining that the first difference value is less than the threshold time value, automatically selecting the first and second digital images for inclusion within a first stack of the plurality of stacks; in response to determining that the second difference value is greater than the threshold time value, automatically selecting the third digital image for inclusion within a second stack the plurality of stacks; wherein the first stack does not include the third digital image; wherein the second stack does not include either the first digital image or the second digital image; wherein the method is performed by a computing device.
