1. Navigate to any webpage with images
2. Right-click on an image
3. Select "Send to ComfyUI (no workflow)" from the context menu
4. The image will be uploaded to ComfyUI (but no workflow will be queued)

5. The extension will:
   • Download the image
   • Upload it to your ComfyUI server
   • Queue the selected workflow with the image
   • Show a notification when complete

Workflow Behavior

• If no workflow is configured, the extension will only upload the image to ComfyUI
• If a workflow is configured, the extension will:
  • Upload the image
  • Find the LoadImage node in your workflow (automatically or using your specified node ID)
  • Update the node with the uploaded image filename
  • Randomize all seed values in the workflow (generates new random seeds for every execution)
  • Queue the workflow for execution

How to Get Workflow JSON

1. Open ComfyUI in your browser
2. Load or create your desired workflow
3. Click the "Save (API Format)" button in ComfyUI
4. This will download a JSON file
5. Open the JSON file and copy its contents
6. Paste into the extension's "Workflow JSON (API Format)" field

Troubleshooting

Extension shows "ComfyUI Not Configured"

• Make sure you've entered the ComfyUI server URL in the extension settings
• Verify the URL is correct and includes the protocol (http:// or https://)

"Connection failed" error

• Ensure ComfyUI is running and accessible at the configured URL
• Check if you can access ComfyUI directly in your browser
• Verify there are no firewall or CORS issues
• Use the "Test Connection" button in Advanced Settings to diagnose

Image uploads but workflow doesn't run

• Make sure you've configured a workflow in the Advanced Settings
• Verify the workflow JSON is valid (it should be in API format from ComfyUI)
• Check the browser console for any errors
• Ensure your workflow has at least one LoadImage node

Workflow runs with wrong image

• Specify the exact LoadImage node ID in Advanced Settings
• Make sure the node ID matches a LoadImage node in your workflow JSON
