how can i show resource value for nivo slider for a language

in nivo slider there is this code

this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture1", "Picture 1");
            this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture2", "Picture 2");
            this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture3", "Picture 3");
            this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture4", "Picture 4");
            this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture5", "Picture 5");
            

I added the german language in nopCommerce

the nivo slider show "Plugins.Widgets.NivoSlider.Picture1" for picture 1 when the resource item "Plugins.Widgets.NivoSlider.Picture1" is already in german language resources.

how to show the value for resource item Plugins.Widgets.NivoSlider.Picture1 in other non english languages?

Just add appropriate string resources here:
admin area -> Configuration -> Languages - Choose language - View string resources -> Add new record
In this case 'Resource name' field is 'Plugins.Widgets.NivoSlider.Picture1' and value is what you want to see in result.
