Save image with generation metadata in ComfyUI

Allows you to save images with their generation metadata. Includes the metadata compatible with Civitai geninfo auto-detection. Works with PNG, JPG and WEBP. For PNG stores both the full workflow in comfy format, plus a1111-style parameters. For JPEG/WEBP only the a1111-style parameters are stored. Includes hashes of Models, LoRAs and embeddings for proper resource linking on civitai.

You can find the example workflow file named example-workflow.json.

You can also add LoRAs to the prompt in \<lora:name:weight> format, which would be translated into hashes and stored together with the metadata. For this it is recommended to use ImpactWildcardEncode from the fantastic ComfyUI-Impact-Pack. It will allow you to convert the LoRAs directly to proper conditioning without having to worry about avoiding/concatenating lora strings, which have no effect in standard conditioning nodes. Here is an example:

This would have civitai autodetect all of the resources (assuming the model/lora/embedding hashes match):

How to install?

Method 1: Manager (Recommended)

If you have ComfyUI-Manager, you can simply search "ComfyUI Image Saver" and install these custom nodes.

Method 2: Easy

If you don't have ComfyUI-Manager, then:

• Using CLI, go to the ComfyUI folder
• cd custom_nodes
• git clone git@github.com:alexopus/ComfyUI-Image-Saver.git
• cd ComfyUI-Image-Saver
• pip install -r requirements.txt
• Start/restart ComfyUI

Customization of file/folder names

You can use following placeholders:

• %date
• %time – format taken from time_format
• %model – full name of model file
• %basemodelname – name of model (without file extension)
• %seed
• %counter
• %sampler_name
• %scheduler
• %steps
• %cfg
• %denoise
