Translation with loco translate

Hello,
I try to translate some strings into french with loco translate but nothing happens.

I want to translate :
– review now (button)
– Choose pictures*
– (maxsize:
– kB, max files:
– with images
– verified
– all stars

I tried with, but nothing.
– languages/loco/plugins/woocommerce-photo-reviews-fra.po
– languages/plugins/woocommerce-photo-reviews-fra.po
– plugins/woocommerce-photo-reviews/languages/woocommerce-photo-reviews-fra.po
Or maybe could I translate it from the code ?

Can you please help ?

Regards,
