I have a bunch of images that I have to manually merge in stacks of 3 together every time. They are all ordered by an alphanumeric filename, so I'm wondering if it's possible to merge them stacked automatically in a batch process in a way that I can set the name of the files so they are named and numbered correctly in a folder.
The images are all the same size, 3840 x 2160 and the stacked image is always the merged size of the images one beneath the other in a stack of three, 3840 x 6480, I have some images as an example. Is it possible to do it in a batch or at least semi-automatically in an action?
3 I can do with a File renamer so it's the least important one, please if you can do it without number 3

Here is an updated 1.1 version, saving to a "Render" sub-folder in the input folder as PNG using a prompt for the base file name with zero padding sequential numbering:

You will need a script, such as here:
Simply change the default setQty variable from 2 to 3.
var setQty = 2;
This will stack one layer over the other in sets of 3 images.
A simple action can be created to make the canvas 300% in height and to move the layers into vertical position:
The script has placeholder code to run a named action set and action before saving.

The following script is complete for your use case, no need for an action to be run by the script:

I'm happy to make changes as needed if further refinement is required.

Thank you, this is pretty much what I needed. If I may tell you just 3 refinements that would make the script even better for me:
1- The script asks me to select a folder where I want the new files to be saved. If possible I'd like the files to automatically be sorted out in a subfolder that would be created inside the folder where the original images were. The subfolder can be called Render.
2 - The files are being saved as PSD files, if possible I'd like them to be saved as PNGs
3- The file names being choosen are the "name of the third image being stacked" + "_x3-Sets", is it possible for the script to ask me a string to name the generated files and number them with "_0001" and so on?
Basically ask me for to type a name, if I type FileS1 it will name the first file generated would be called FileS1_0001 and the second FileS1_0002 and so on...
Again thank you for the help, you're amazing!

It's awesome that it's even possible to an automatic naming, something happened with the new script though. I don't know if I did something wrong but in this new script is saves the files all backwards, that meaning the last 3 images sorted in an alpha numeric number become the first new stacked image on the new files (their position on the canvas are still correct though). On the previous script the files were being made correctly. The script even renders the images backwards, it starts with the last images and the previous one started with the first images, so I don't know what is happening there.
Except for that everything is working correctly.

I didn't intentionally change any code that would have affected file processing sequence or layer stacking order. I had a quick look and couldn't see any differences that would account for this.
You could try changing from:
fileList.sort();
To:
fileList.sort().reverse();

You can use a scripting language like Python to achieve this. Here's a step-by-step approach:
Install the required libraries by running the following command in your terminal:
pip install numpy opencv-python
import os
import cv2
import numpy as np
# Set the input and output directories
input_dir = 'input_images/'
output_dir = 'output_images/'
# Create the output directory if it doesn't exist
if not os.path.exists(output_dir):
os.makedirs(output_dir)
# Get the list of image filenames in the input directory
image_files = sorted([f for f in os.listdir(input_dir) if f.endswith('.jpg')])
# Iterate over the image files and merge them in stacks of three
for i in range(0, len(image_files), 3):
# Load the three images
image1 = cv2.imread(os.path.join(input_dir, image_files[i]))
image2 = cv2.imread(os.path.join(input_dir, image_files[i + 1]))
image3 = cv2.imread(os.path.join(input_dir, image_files[i + 2]))
# Stack the images vertically
merged_image = np.vstack((image1, image2, image3))
# Save the merged image with a new name
output_filename = f"merged_{i // 3}.jpg"
cv2.imwrite(os.path.join(output_dir, output_filename), merged_image)
print("Image merging completed.")
python image_merge.py
The script provided automatically merges images in stacks of three, saving the merged images with a "merged_" prefix and a stack index in the output directory. Input images should be named to ensure correct alphanumeric sorting. The script supports JPEG format by default but can be modified for other formats.
This will help you.
