Probleme de resize des thumbnails galerie photo...

Marsh Posté le 10-11-2005 à 10:02:19

salut,

voila j'expose dessuite mon probleme:

J'ai télécharger un petit script qui permet facilement de créé un galerie photo. A partir d'un dossier nommé "images" il prend les photo qui se trouvent dedans et crée automatiquement une page HTML avec des thumbnail aligné.

Le probleme (c'est pas trop un probleme) c'est que les thumbnails n'apparaissent pas en entier... il apparait que une petite partie de la photo et en plus en 80x50 alors que je voudrais un poil plus grand.

Je voudrais que la photo entiere soit vue en thumbnail.

Exemple ici : http://justine.franck.free.fr/scri [...] photos.php

Merci de m'aider, voici le code de la page qui à l'include pour exécuter le script :

Citation :

<?
include("./bolGallery.php" );
bolGallery("./images/", 7, 90, 85, 1);
?>

et la page du script :

C'est pas dans les pratique de ce forum d'aider à débugguer un script qui n'est pas fait par l'auteur du message.
Mais si tu veux t'en sortir, ca serait peut être bien de lui spécifier quel type de miniature tu veux (6 éme paramettre de la fonction) vu que par défaut, c'est juste un bout d'image qui est utilisé. A toi de lire ce code pour savoir ce qu'il faut y mettre.

Si tu n'as pas déjà trouvé la réponse, il faut ajouter l'argument 1 à la fonction bolGallery().
Soit bolGallery("./images/", 5, 80, 50, 1) où 5 est le nombre de colonnes de l'album, 80 la largeur de la miniature, 50 sa hauteur (tu mets ce que tu veux), et 1 ou 0 pour le mode normal ou créatif (par défaut 0, miniatures partielles).
Pour régler les espaces entre les miniatures, édite bolGalleryCreate() et modifie le tag HTML <TABLE> avec par ex. le cellspacing à 2.
