GIF animé Redimensionner et télécharger

Question

J'ai un problème avec ma forme de téléchargement d'image. quand je télécharge gif animé il dosent semble animer plus. est-il possible de résoudre ce problème? ou si je peux juste passer le redimensionnement de l'extension .gif et seulement redimensionner d'autres types de fichiers comme .jpg, png etc cela ira aussi bien.

La bibliothèque GD et ses fonctions associées ne peuvent pas gérer gifs animés. Si vous pouvez installer le Imagemagick library, vous pouvez manipuler des gifs animés avec ces fonctions.
