My bad, fixed it.

I’ve heard good things about xnview

It has nice ui, support, is cross-platform and foss

Edit: it is freeware, not foss!

I am from EU so you are probably fine.

On my rooted LineageOS ROM it works just fine, just gives a warning when starting it for the first time that I am using a “rooted device” and how my “security might be compromised” but it lets you continue and doesn’t show it ever again.
