This ComfyUI workflow is designed to efficiently combine four separate images into a cohesive 2x2 grid, resulting in a single 2048x2048 output image. The workflow utilizes several key nodes, including LoadImage, ImageStitch, SaveImage, and ResizeImageMaskNode. The process begins by loading the four input images, which are then resized if necessary to ensure uniformity. The ImageStitch nodes are used to first combine the top-left and top-right images into a single row, and then the bottom-left and bottom-right images into another row. Finally, these two rows are stacked vertically to form the complete grid. This workflow is particularly useful for creating composite images or collages, where the uniform size and alignment of images are crucial.
