Save Image - Save image batches to disk

Node Purpose: Save Image writes an IMAGE batch to the ComfyUI output or temp directory and returns the saved absolute file paths. It supports configurable filename prefixes and optional prompt/workflow metadata embedding.

Inputs

Name	Port	Type	Default	Range	Description
image	optional	IMAGE	-	-	Image batch to save; when absent, the node finishes with an empty output.
filename	-	STRING	image/ComfyUI	-	Save prefix or absolute path; typically supports date placeholders (e.g. %date:yyyy-MM-dd%).
auto_increment	-	BOOLEAN	true	-	When true, uses auto-incrementing numbers; when false, uses fixed filename and overwrites.
save_output	-	BOOLEAN	true	-	Save to output directory when enabled; skip saving to disk when disabled.
save_metadata	-	BOOLEAN	true	-	Embed prompt/workflow metadata when enabled.

Outputs

Name	Type	Description
file_path	STRING	Absolute paths joined by newline, one per saved image.

Features

• Output routing: choose output directory or temp directory via save_output.
• Metadata control: toggle embedding of prompt and extra_pnginfo via save_metadata.
• Stable naming: uses ComfyUI path allocation to generate unique filenames.
• UI preview: shows a Saved Images gallery for the saved results.

Typical Usage

• Save final results to the output directory while keeping intermediate steps in temp.
• Set save_metadata=false when exporting images for external pipelines.

Notes & Tips

• The node returns absolute paths; multiple images are separated by newline.
• The node serializes filename allocation to keep counters consistent under concurrent execution.
