Bonjour,
"Un peu" lourd, effectivement
Bon avant de passer aux choses sérieuses, j'ai 3 erreurs javascript en chargeant ton site.

Tu appelles énormément de fichiers externes ! Essaie d'en fusionner quelques-uns. Ensuite, les fichiers js, si possible, s'appellent juste avant </body> pour ne pas bloquer le chargement du reste de la page.

Ensuite, débarasse toi de tous ces trucs là ! Je ne pense pas qu'ils soient utiles au départ (j'ai l'impression que c'est pour un diaporama ?), personne ne va rester 20 ans sur ta home pour voir défiler des images miniatures aléatoirement en plus
Je pense que si tu corriges déjà tout ça, le temps de chargement —effectivement assez long— sera considérablement réduis.
