Display an image depending on the current URL

I am setting up a website and want to display a different image depending on the current page URL

If http://webpage.com/test/en/ then display image 1
If http://webpage.com/test/fr/ then display image 2
If http://webpage.com/test/nl/ then display image 3

New to this but managed to do something similar but there were only 2 options! any help appreciated:

<?php if ($autoshowroom_video) { ?>
<iframe src="<?php echo esc_url($autoshowroom_video); ?>
?autoplay=1&loop=1&modestbranding=1&showinfo=0&rel=0&iv_load_policy=3&controls=0" width="310" height="205" frameborder="0"></iframe>
<?php } else { ?>
<video width="100%" height="auto" autoplay loop muted>
<source src="https://test.co.uk/Promo.mp4" type="video/mp4" />
<?php } ?>
