Custom ComfyUI Workflow Wallpapers

It allows you to set custom background images for workflows.

Install

Copy this folder into your ComfyUI custom_nodes directory and restart ComfyUI:

custom_nodes/comfyui-workflow-background

Right-click an empty canvas area.
Choose Change Workflow Background.
Pick an image (browse, drop, or paste), adjust opacity / fit / position, press Close.
Save the workflow (Ctrl+S) so the background setting is stored.

The image is NOT embedded in the workflow JSON - only the file name is stored in the workflow extra data.
The image is uploaded to the ComfyUI input/backgrounds folder.

Saved under extra.canvasBackgroundImage in the workflow JSON:

{
  "filename": "my-bg.png",
  "subfolder": "backgrounds",
  "type": "input",
  "opacity": 80,
  "fit": "cover",
  "position": "center"
}
