How to use the script

The interface has three sections: Input 1, Input 2, and Output. Choose the folders and click the OK button to begin. A progress bar is displayed as images are processed.

Section 1: Input 1

Folder — select a folder of images. The layers of each image in the folder will become the highest layers in the output file.

Section 2: Input 2

Folder — select a folder of images. Any image found that matches the name of an image from input folder 1, the layers of the image are copied to the output image below the layers of input image 1.

Section 3: Output

Folder — select a folder to which output images are saved. Each image is saved the same name as the two input images but in Photoshop format and the extension PSD.

When files are output, any existing files of the same name in the output folder are replaced without alert.

IMPORTANT: scripts are developed for the latest Adobe Creative Cloud applications. Many scripts work in CC 2018 and later, even some as far back as CS6, but may not perform as expected, or run at all, when used in versions prior to 2018. Photoshop features Select Subject and Preserve Details 2.0 definitely fail prior to CC 2018 (version 19) as the features do not exist in earlier versions. For best results use the latest versions of Adobe Creative Cloud applications.
