J'ai besoin d'obtenir le chemin de l'image qui se trouve sur www.mysite.com/themes/mytheme/img/image.png
==================================================
J'ai trouvé la réponse ici: http://prestalab.ru/wiki/peremennye-v-shablonax .
Le chemin d'accès à l'image dans mon thème sera: { $ tpl_dir } img/myimage.png
$tpl_uri
renverra le chemin du thème actuel par rapport à la racine Web.
Voici quelques autres variables globales mises à disposition par PrestaShop qui peuvent être utiles:
$img_ps_dir // the PrestaShop image directory
$img_cat_dir // current category's images directory
$img_lang_dir // current language's images directory
$img_prod_dir // current product's images directory
$img_manu_dir // current manufacturer's images directory
$img_sup_dir // current supplier's images directory
$img_ship_dir // current carrier's (shipping) images directory
$img_dir // current theme’s images directory
$css_dir // current theme’s CSS directory
$js_dir // current theme’s JavaScript directory
$tpl_dir // current theme’s directory (physical path on machine)
$tpl_uri // current theme's directory (web-root relative path)
$modules_dir // modules directory
$mail_dir // mail templates directory
$pic_dir // pictures upload directory
Parfois, il suffit de regarder le code pour voir toutes les variables de base affectées:

Sur PS 1.6, j'ai constaté que je devais ajouter une variable smarty pour obtenir l'URI de mon thème. Dans classes/controller/FrontController.php sur la ligne 333 où tpl_dir est défini, j'ai ajouté cette ligne ci-dessous:
'tpl_uri' => _THEME_DIR_,
qui renvoie le chemin du thème.
Il existe une variable globale smarty pour le dossier mytheme img qui est - img_dir
