ComfyUI-ImageCompare Node

A simple custom node for ComfyUI that allows you to compare two images (or batches of images) side-by-side within the UI.

This node is useful for visually inspecting differences or similarities between images generated at different steps of a workflow, or comparing outputs from different models or prompts.

Acknowledgements

Much of the foundational code for handling image saving and previews was adapted from the excellent rgthree-comfy custom nodes by rgthree. Their work provided a great starting point for the UI display logic.

Features

Displays two input images (A and B) next to each other.
Supports single images and batches.
Integrates directly into the ComfyUI interface.

Installation

Navigate to your ComfyUI custom_nodes directory:
```
cd ComfyUI/custom_nodes/
```

Clone this repository:

git clone https://github.com/rakki194/ComfyUI-ImageCompare.git

Restart ComfyUI.

Alternatively, you can download the .py files (and any web directory files if applicable) and place them inside a folder named ComfyUI-ImageCompare within your custom_nodes directory.

Usage

Add the "Image Compare (🐺)" node to your workflow (you can find it under the "ComfyUI-ImageCompare" category or by searching).
Connect an image output to the image_a input.
Connect another image output to the image_b input.
Queue your prompt. When the workflow reaches the Image Compare node, the images will be displayed side-by-side in the node's interface.

Note: This node saves temporary preview images similar to the built-in PreviewImage/SaveImage nodes to display them in the UI.
