ComfyUI Node: Join Images

Join Images:

The JoinImages node is designed to seamlessly combine two images either vertically or horizontally. This node is particularly useful for creating composite images, where you want to place one image next to another in a specified direction. By leveraging this node, you can easily merge images to create a single cohesive visual, which can be beneficial for various artistic and design purposes. The node simplifies the process of image concatenation, ensuring that the images are aligned correctly based on the chosen direction, thus saving you time and effort in manual editing.

Join Images Input Parameters:

image_1

This parameter represents the first image that you want to join. It is one of the two images that will be combined to form a single output image. The quality and dimensions of this image will directly impact the final result.

image_2

This parameter represents the second image that you want to join. Similar to image_1, this image will be combined with the first image to create the final output. Ensure that the dimensions of this image are compatible with image_1 for optimal results.

direction

This parameter determines the direction in which the two images will be joined. It accepts two options: Vertical and Horizontal. Choosing Vertical will stack the images one on top of the other, while selecting Horizontal will place them side by side. The direction you choose will affect the overall layout of the combined image.

Join Images Output Parameters:

Image

The output parameter is a single combined image resulting from the joining of image_1 and image_2 in the specified direction. This image will inherit the properties of the input images and will be aligned based on the chosen direction, providing a seamless composite visual.

Join Images Usage Tips:

• Ensure that the dimensions of image_1 and image_2 are compatible to avoid any unexpected results or misalignment in the final combined image.
• Use the Vertical direction to create a stacked effect, which can be useful for creating banners or posters.
• Use the Horizontal direction to place images side by side, ideal for comparison visuals or panoramic effects.

Join Images Common Errors and Solutions:

Labels/Images don't add up!

• Explanation: This error occurs when the number of images does not match the expected count based on the provided labels.
• Solution: Ensure that the number of images you are trying to join matches the expected count. Double-check the input images and labels to ensure they are correctly specified.

Incompatible image dimensions

• Explanation: This error occurs when the dimensions of image_1 and image_2 are not compatible for the chosen direction.
• Solution: Verify that the dimensions of both images are compatible. For vertical joining, the widths should match; for horizontal joining, the heights should match. Resize the images if necessary to ensure compatibility.
