This node saves a list of images to a specified folder within ComfyUI’s output directory. It takes multiple images as input and writes them to disk with a customizable filename prefix.

Inputs

Parameter	Data Type	Required	Range	Description
images	IMAGE	Yes	N/A	List of images to save.
folder_name	STRING	No	N/A	Name of the folder to save images to (inside output directory). The default value is “dataset”.
filename_prefix	STRING	No	N/A	Prefix for saved image filenames. The default value is “image”.

Note: The images input is a list, meaning it can receive and process multiple images at once. The folder_name and filename_prefix parameters are scalar values; if a list is connected, only the first value from that list will be used.

Outputs

This node does not have any outputs. It is an output node that performs a save operation to the filesystem.
