Image Batch Multi(ImageBatchMulti)

The Image Batch Multi node technically works by dynamically creating input ports.

The Image Batch Multi node is a tool for image batching. Its core function is to merge multiple independent images into a single batch. This allows you to input multiple image samples as a whole into subsequent workflows for unified processing, such as batch generation or batch conversion.

Node Functionality

This node technically works by dynamically creating input ports. You first set the desired number of images using the inputcount parameter, then click the "Update" button. The node interface will then generate a corresponding number of image input slots. Internally, it calls ComfyUI's built-in ImageBatch node to concatenate the input image tensors along the batch dimension, ultimately outputting a batch tensor containing all input images.

Control Parameters (Parameters)

Usage Scenarios

In practical workflows, this node is very useful when you need to feed multiple images with different content but identical dimensions (such as a set of portraits of different characters, or multiple design variants) into the same sampler or image processor. For example, you can first generate multiple sketches, then use this node to merge them, and subsequently apply the same upscaling or stylization filter all at once, enabling efficient batch processing.

Notes

Please note that the dimensions (height, width, and number of channels) of all input images must be exactly the same; otherwise, the concatenation operation will fail. Additionally, the number of input images cannot exceed the maximum value set by the inputcount parameter.
