Gallery Not Responsive

I have a responsive layout site and I keep having text go behind the dynamic gallery if the window is re-sized and the gallery is wider than 160px.

I have tried to change the gallery to %percentage, but every time I do and click save, it just reverts to px.

I am using the Artificer Woocommerce Theme.

Any help on this would be appreciated.
