How to automatically add two images into layer in a single PSD or TIFF then save?

On a related note, I built a generic script with a GUI – "Stack Documents to Sets of N Layers" (this script doesn't retain the Background layer of the first doc, the expectation is that files are flattened or have single layers):

I have cleaned up the code a little bit from the generic script previously posted and changed over to layered TIFF output:

* This script requires input files from a single folder to be alpha/numeric sorting in order to stack in the correct set quantity. 

* A minimum of 2 or more files per stack is required. The quantity of input files must be evenly divisible by the stack quantity.

@hosongn52153496 – Try the following generic script. It saves to PSD, however, it could also save to layered TIFF or flattened JPEG etc. Let me know if any changes are required for your specific use case.

Stack N Number of Document Sets to Layers - Top Level Folder.jsx
Stephen Marsh
8th June 2024 Version
https://community.adobe.com/t5/photoshop-ecosystem-discussions/script-to-automate-load-files-into-stack/m-p/13499068

A generic, skeleton "framework" script to help fast-track development of similar scripts for combining multiple "sequence" single-layer files to layers.

This script requires input files from a single folder to be alpha/numeric sorting in order to stack in the correct set quantity. 

Example: File-01.jpg File-02.jpg etc, FileA1.tif FileA2.tif etc, File1a.tif File1b.tif etc.

A minimum of 2 or more files per stack is required. The quantity of input files must be evenly divisible by the stack quantity.

A named action set and action can be set on line 159 to "do something" with the stacked layers.

This topic comes up regularly, I'll post the code later.

Another neat feature of using Sef's idea about "Loading files into Stacks" is that it also loads the file name as th layer name so you can see exactly which layers go toether!

Hi @hosongn52153496 ,

Yep, I can see that would be painful. Luckily there's an easy solution:
Just go to File>Scripts>Load Files into Stack...
You can run on either files that are open in Photoshop, or files you select on your hard drive.
Give it a try and see which way you think might be the quickest for your workflow. Just click the browse button to navigate to images on your hard drive.
You might also record an action that selects File>Open so you can select 2 files, then runs the Load Files into Stack script and assign a shortcut key to it. That way you could just hit an F-Key, choose 2 files, OK, Load Open Files, and Save. Viola.
Let us know what works for you!
Thanks,

Sef
