Conditional Shortcode Based on Language

Things like emails sent to users by different plugins can not be translated because they do not appear in the front-end.

For these other types of content you can display content based on language using the shortcode:

[trp_language language="en_US"] English content only [/trp_language]

An important use case of the conditional shortcode is for translating images, basically displaying different images for different languages.

[trp_language language="en_US"] 
<img src="https://example.com/image_en.png" /> [/trp_language]
[trp_language language="fr_FR"]
<img src="https://example.com/image_fr.png" />
[/trp_language]
