ComfyUI Node: Save Image Grid (mtb)

Save Image Grid (mtb):

The Save Image Grid (mtb) node is designed to help you efficiently organize and save multiple images into a single, cohesive grid layout. This node is particularly useful for AI artists who need to present a collection of generated images in a structured format, making it easier to visualize and compare the results. By automatically calculating the optimal grid size based on the number of images, this node ensures that your images are neatly arranged without any manual adjustments. The primary goal of this node is to streamline the process of saving and displaying multiple images, enhancing your workflow and allowing you to focus more on the creative aspects of your projects.

Save Image Grid (mtb) Input Parameters:

images

This parameter expects a list of images that you want to include in the grid. Each image in the list will be placed in the grid based on its order in the list. The quality and resolution of the final grid image will depend on the quality of the individual images provided. There is no strict limit on the number of images, but keep in mind that a very large number of images may result in a very large grid image, which could be difficult to manage or view.

filename_prefix

This parameter allows you to specify a prefix for the filename of the saved grid image. The default value is "ComfyUI". This prefix helps in organizing and identifying the saved grid images, especially when you are working with multiple grids or batches of images. You can customize this prefix to match your project or naming conventions.

save_intermediate

This boolean parameter determines whether intermediate images should be saved during the grid creation process. The default value is False. If set to True, the node will save intermediate images, which can be useful for debugging or for creating step-by-step visual documentation of the grid creation process. However, enabling this option may result in additional storage usage.

Save Image Grid (mtb) Output Parameters:

This node does not produce any direct output parameters. Instead, it performs the action of saving the grid image to the specified output directory. The saved image can then be accessed and used as needed.

Save Image Grid (mtb) Usage Tips:

• Ensure that all images in the list have the same dimensions to avoid any alignment issues in the final grid.
• Use a meaningful filename prefix to easily identify and organize your saved grid images.
• If you are working with a large number of images, consider disabling the save_intermediate option to save storage space and reduce processing time.

Save Image Grid (mtb) Common Errors and Solutions:

"Image list is empty"

• Explanation: This error occurs when the provided list of images is empty.
• Solution: Ensure that you provide a non-empty list of images to the node.

"Inconsistent image dimensions"

• Explanation: This error occurs when the images in the list have different dimensions.
• Solution: Make sure all images have the same width and height before passing them to the node.

"Failed to save image"

• Explanation: This error occurs when the node is unable to save the grid image to the specified directory.
• Solution: Check the output directory path and ensure that you have write permissions. Verify that there is enough storage space available.
