Triggering Image Processor Pro, Photoshop 2025

To be clear, I am only using Photoshop in this scenario to launch image processor pro to create my JPEGs automatically. Here's the overview of the intended workflow: 

The starting point: document TIF scans from an Epson version 750 flatbed scanner, via Epson Scan 2.

Desired endpoint: tiffs and downscaled JPEGs catalogued in Lightroom classic, with the JPEGs synced to a collection for remote client review. After review, I will make batch adjustments followed by individual fine tuning.

this workflow is completely sorted out from an automation standpoint except for one step, which is the creation of the JPEGs before auto-import into Lightroom. Because there will be hundreds of docs, and out of curiousity, I want to automate this missing piece.

I am aware of Photoshop and Lightroom tools. I am also aware that Vuescan , should I choose to spend 150 bucks, allows for dual output of formats from the scanner. But I thought certainly with all the tech behind Photoshop and Lightroom and Mac Automator and Applescript, certainly something like should be possible if not easy. A ChatGPT–created Apple script does in fact open Photoshop when it detects that a Tif has landed in a specified folder but it does not trigger image processor.

I have also confirmed that image processor Pro manually launched inside of Photoshop does what I want, and I’ve made a preset. It just doesn’t auto launch, and I’m trying to sort out why.
