An image may be divided into multiple portions or sub-images using division lines. To facilitate this process, the division lines may be drawn with user input in a single direction. The image may then be rotated to allow a user to draw lines extending in other directions using the same user input direction. In some instances, rotation may be automatically performed upon drawing of a division line, deletion of a sub-image, receiving a specified user command or type of user input and the like. Additionally or alternatively, upon rotating the image a first time in one direction, a subsequent rotation of the image may be performed in an opposite direction. The first rotation and the subsequent rotation may be of the same rotation amount. If a sub-image is deleted, a remaining sub-image or sub-images may be resized or otherwise modified to fit within the display.
