ImagePass

The ImagePass node technically implements a "pass-through" function that accepts an input tensor of type IMAGE and, without any internal processing, directly returns it as an IMAGE tensor of the same type.

The ImagePass node is a simple image pass-through node. Its core function is to receive an image input and pass it unchanged to the output, without modifying or processing the image content in any way. It is primarily used for signal transmission and flow control within workflows.

Node Functionality

This node technically implements a "pass-through" function. It accepts an input tensor of type IMAGE and, without any internal processing, directly returns it as an IMAGE tensor of the same type. It supports the standard ComfyUI image tensor format, and its core mechanism is to maintain data integrity and consistency.

Node Parameter Description - ImagePass

Connection Inputs (Inputs)

Parameter Name	Data Type	Required	Default Value	Value Range/Options	Description
`image`	IMAGE	No	-	-	image (Input Parameter): Input the image data to be passed through. This parameter is optional; if not connected, the output will be empty.

Output

Parameter Name	Data Type	Description
IMAGE	IMAGE	IMAGE (Output Parameter): Outputs image data identical to the input.

Usage Scenarios

In complex workflow construction, this node can be used to temporarily interrupt or reorganize node connections. For example, when testing the effect of a specific part of a workflow, an ImagePass node can be inserted to temporarily isolate subsequent processing steps, or to branch the image stream into multiple different processing paths.

Notes

Since this node does not perform any image processing operations, there are no performance or quality usage limitations. Users should note that its output is exactly equivalent to its input; if the input is empty, the output will also be empty.

The ImagePass node is from the ComfyUI-KJNodes node package.
