ComfyDeploy: How ComfyUI Image Saver works in ComfyUI?

What is ComfyUI Image Saver?

Allows you to save images with their generation metadata compatible with Civitai. Works with png, jpeg and webp. Stores LoRAs, models and embeddings hashes for resource recognition.

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for ComfyUI Image Saver and select it
  5. Close the build step dialig and then click on the "Save" button to rebuild the machine

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): image

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

Example:

| filename value | Result file name | | --- | --- | | %time-%basemodelname-%cfg-%steps-%sampler_name-%scheduler-%seed | 2023-11-16-131331-Anything-v4.5-pruned-mergedVae-7.0-25-dpm_2-normal-1_01.png |
