Vovsoft Image Combiner is an image joiner software that you can join multiple images. You can add images individually, drag and drop, or select a folder where they are located and let the application extract all the compatible pictures. All the images are displayed in a list, along with their width and height. You can easily change the image order, and choose whether to merge images vertically, horizontally or in grid layout. Once you do so, pressing the "Combine" button will start creating the collage. The merged image will be saved to your preferred directory. The software also allows you to duplicate selected files so that you can use the same image file multiple times.
