ComfyUI Node: Image Sender

Image Sender:

The ImageSender node is designed to facilitate the seamless transmission of images within the ComfyUI framework. This node is particularly useful for AI artists who need to send images to different parts of their workflow or external systems. By leveraging the ImageSender node, you can easily save images with a specified filename prefix and send them through a prompt server using a unique link identifier. This functionality is essential for maintaining an organized workflow and ensuring that images are correctly routed and processed. The node's primary function, doit, handles the saving and sending of images, making it a powerful tool for efficient image management and communication within your AI art projects.

Image Sender Input Parameters:

images

This parameter expects an image input of type IMAGE. It represents the images that you want to save and send. The images provided here will be processed by the node to generate the desired output.

filename_prefix

This parameter is a string (STRING) that allows you to specify a prefix for the filenames of the saved images. The default value is "ImgSender". This prefix helps in organizing and identifying the saved images, especially when dealing with multiple images in a workflow.

link_id

This parameter is an integer (INT) that serves as a unique identifier for the link through which the images will be sent. The default value is 0, and it can range from 0 to the maximum value allowed by the system (sys.maxsize). This identifier ensures that the images are sent to the correct destination or system.

prompt

This hidden parameter (PROMPT) is used internally by the node to handle additional prompt information. It is not required to be set manually by the user.

extra_pnginfo

This hidden parameter (EXTRA_PNGINFO) is used internally by the node to handle extra PNG information. It is not required to be set manually by the user.

Image Sender Output Parameters:

ui

This output parameter contains a dictionary with the key images, which holds the paths to the saved images. The ui output is essential for further processing or displaying the images within the ComfyUI framework. It ensures that the images are correctly saved and accessible for subsequent steps in your workflow.

Image Sender Usage Tips:

• To keep your workflow organized, use a meaningful filename_prefix that reflects the content or purpose of the images being saved.
• Utilize the link_id parameter to ensure that images are sent to the correct destination, especially when working with multiple nodes or external systems.
• Although the prompt and extra_pnginfo parameters are hidden, understanding their role can help in advanced configurations and troubleshooting.

Image Sender Common Errors and Solutions:

Invalid image file: <image>

• Explanation: This error occurs when the provided image file is invalid or cannot be found.
• Solution: Ensure that the image file path is correct and that the file exists. Verify that the image file is not corrupted and is in a supported format.

[WARN] ComfyUI-Impact-Pack: ImageReceiver - invalid 'image_data'

• Explanation: This warning indicates that the image data provided is invalid or cannot be decoded.
• Solution: Check the format and encoding of the image data. Ensure that the image data is correctly base64 encoded and that it includes the necessary metadata.

Error sending image: <error_message>

• Explanation: This error occurs when there is an issue with sending the image through the prompt server.
• Solution: Verify the network connection and ensure that the prompt server is running and accessible. Check the link_id and other parameters to ensure they are correctly configured.
