Photoshop automated script to replace image

Hello,

I am looking for some script or instructions to replicate an action in photoshop. I have a PSD template which has a couple of images that are replaced over a part of the design. I use the REPLACE CONTENTS after I right click on the layer to be changed.

I then choose a new JPEG and the file is saved.

I want this automated so I can choose a lot of JPEGS in a folder and each one will replace the layer and then saved as a new JPEG.

Thanks.
Kevin
