How to bulk delete secondary product images on my site?

[LeFlo]

Hello,

I have 40 products for a collection,
on each product sheet: 2 photos,
and I need to remove the second photo from all these product sheets.

Doing it by hand is much too long
I know Bulk Edit Product apps, and even Bulk Edit Image apps, but they don't allow you to delete, just add images.

does anyone know an app (or trick) that can do this?
