+### Canvi d'imatge en passar el cursor
+
+La imatge mostrada canvia quan l'usuari passa el cursor per sobre. Útil per a comparacions d'abans i després, per exemple.

+{{ image_hover(default_src="img/edited.webp", hovered_src="img/raw.webp", default_alt="Foto editada", hovered_alt="Foto original") }}

+
+### Canvi d'imatge via clic
+
+Mostra una imatge i canvia a una diferent en fer clic. Ideal per destacar diferències o cridar l'atenció sobre detalls.

 ### Imatge d'amplada completa
 
 La imatge s'expandirà per coincidir amb l'amplada de la capçalera, que normalment és més ampla que el text de l'article (excepte en mòbil/finestres petites).
