Question

Image processing

Hello. You need to batch crop hundreds of product images that have a lot of extra white background. Those. there are these pictures:

They need to cut off the extra white indents to the product images themselves. I've done this before, but I don't remember what I used for it. Perhaps it was the FastStone Photo Resizer program, but now I don’t see these settings.
Thanks in advance

Answer 3

In Photoshop, there is the concept of action - these are scripts of repetitive actions.
You can write your own action consisting of sequential commands and apply it to any images.
What you need is done with a single command - image -> trim and this is the result
. Record this Action and execute it as many times as you like.
