Create Panorama image
Click on the Image Menu, then Create Panorama image. A dialog allows you to create a panorama image.
You can add single images vertically or horizontally. The first image in the chain will be used as the base for the next images.
There is also an option to insert filenames into the panorama image (top left corner of the single image) or add some empty space between the images. 0 pixels means no space (default).
