Workflow Help! Batch Load files into Layers and save possible?

I dont know ive been looking online for ages now trying but it seems impossible to save as a .psb in a script? i stumbled across that last line in another forum and problem solved the awesome one you have done.

Here, try this.

I dont have CR2 of NEF files to test this on, so not sure if it works 100%. Let me know if it does:)

You beautiful genius!

Image sizes are all the same. however This only seems to work with Jpegs, Anyway to use raw images and load with default raw setting/Preset set as defualt)

The folder approach you have will work perfectly,

Out of curiosity is it possible to target only rated images , for example only load files with a 1 star rating and ignore the rest?

This would save relocating selected images?
