ComfyUI Node: Image Saver

Image Saver:

Zuellni Image Saver is a versatile node designed to save images generated or processed within the ComfyUI environment. This node is essential for AI artists who need to store their creations in various formats, ensuring that their work is preserved and easily accessible. The node supports multiple image formats, including GIF and grid layouts, and offers optimization options to balance quality and file size. By automating the image-saving process, Zuellni Image Saver streamlines your workflow, allowing you to focus more on creativity and less on technical details. Whether you are saving individual images or creating animated sequences, this node provides a reliable and efficient solution.

Image Saver Input Parameters:

images

This parameter accepts a batch of images that you want to save. The images should be in a tensor format, typically generated or processed by other nodes within the ComfyUI environment. The quality and format of the saved images will depend on the settings you choose for other parameters.

output_dir

This parameter specifies the directory where the images will be saved. It should be a valid path on your filesystem. If the directory does not exist, the node will create it. This ensures that your images are organized and stored in a location of your choice.

format

This parameter determines the format in which the images will be saved. Options include "gif" for animated sequences and "grid" for a grid layout of multiple images. The choice of format affects how the images are displayed and can be optimized for different use cases.

optimize

This boolean parameter indicates whether to optimize the saved images. Optimization can reduce file size while maintaining quality, making it ideal for web use or storage efficiency. The default value is typically set to False.

fps

This parameter is relevant when saving images in GIF format. It specifies the frames per second for the animation, affecting the playback speed. A higher FPS results in a smoother animation, while a lower FPS can create a more staggered effect. The default value is usually set to a moderate speed.

masks

This optional parameter allows you to include masks with your images. Masks can be used for various purposes, such as highlighting specific areas or creating transparency effects. If provided, the masks should be in a compatible tensor format.

Image Saver Output Parameters:

None

The Zuellni Image Saver node does not produce any direct output parameters. Instead, it performs the action of saving images to the specified directory. The success of this operation can be verified by checking the output directory for the saved files.

Image Saver Usage Tips:

• Ensure that the output_dir parameter is set to a valid and accessible directory to avoid any file-saving errors.
• Use the optimize parameter to reduce file sizes, especially when saving images for web use or when storage space is limited.
• When creating GIFs, experiment with different fps values to achieve the desired animation speed and smoothness.
• If you need to save images with specific areas highlighted or transparent, make sure to provide appropriate masks using the masks parameter.

Image Saver Common Errors and Solutions:

"Invalid output directory"

• Explanation: The specified output_dir is not a valid path or is inaccessible.
• Solution: Ensure that the output_dir parameter is set to a valid directory path and that you have the necessary permissions to write to this location.

"Unsupported image format"

• Explanation: The format parameter is set to an unsupported value.
• Solution: Verify that the format parameter is set to one of the supported options, such as "gif" or "grid".

"Failed to save images"

• Explanation: An error occurred during the image-saving process, possibly due to invalid image data or insufficient disk space.
• Solution: Check the input images for any issues and ensure that there is enough disk space available in the output_dir. If the problem persists, try saving a smaller batch of images to isolate the issue.
