Mockup // how to export multiple images at once (photoshop)

Hi all,

I have a Photoshop question, but my PS knowledge doesn’t reach far.

My question

I use a mockup template that uses a ‘smart object’ where I can add multiple photo’s at once. But I still have to select every image one by one before I can save them as .jpg (very time consuming).

Is there a way to batch export the mockup with all the photo’s I added to the ‘smart object’?

I read something about adding ‘scripts’ to Photoshop…no idea how that should work.

Hope someone can help with this.

Thanks!
