Hi,
I see only the image name added inside HTML but not the path of the image.
Below code example data-src="3.jpg".
The theme developer can fix this.
<a href="https://carinhosshop.com/es/" class="dropdown-item" data-iso-code="es">
<img class="lazy" data-src="3.jpg" alt="es" width="16" height="11">
Espanhol
</a>
Attached screenshot for your reference.
