Same problem.
Fullscreen mode, next or prec picture, each of them is downloaded twice.

You can see that on your demo https://stackblitz.com/edit/ngx-gallery

Angular : 13.1.0

Thanks

@nicosaliagas In the stackblitz, we use the same image URL for both thumbnail and main slider, so that is probably the reason why you see it twice
