Antes de nada quiero saludar a todos los miembros de este foro al cuál me acabo de inscribir.
Bueno pues tengo un pequeño problema que me imagino que será eso, pequeño, pero debido a mis pocos conocimientos de php pues me estoy agobiando demasiado. Estoy trabajando con una galería de imágenes en flash con administrador de imagenes online, se llama Flash Image Gallery
Código HTML:
http://www.flashimagegallery.com/
y la verdad es que lo estoy usando primero por ser gratuito y segundo por las facilidades para gestionar la propia galería ( para que el propio cliente se la organize).
Bueno pues el quebradero de cabeza lo tengo con los permisos de las imagenes que subo al servidor, por defecto los permisos aparecen en 600 y cuando accedo a través del navegador pues no me permite acceder a dichas imagenes aunque los thumbnails no dan este problema, se cargan bien en la galerí ay son accesibles desde el navegador. He estado revisando los códigos en php que gestionan la galería pero no he encontrado nada ni he visto donde poder añadir algún comando para establecer permisos de chmod a 777.
Os dejo a continuación el código a ver si alguno de vosotr@s ha tenido el mismo problema o es capaz de ver que es lo que faltaría añadir (o restar).
Gracias de antemano.
