Bonjour,
j'utilise le code ci-dessous pour récupérer la taille d'une image sur le serveur. Cela marche très bien sur un serveur IIS, mais avec Apache+Chilisoft rien à faire... La page ne se charge pas et aucun message d'erreur (ça plante carrément le serveur !)
Quelqu'un voit où est le pb ?
Merci d'avance à celui (ou celle !) qui me sauvera la vie !!!!!!!!!!!
Cordialement, Tristan

'::: This routine will attempt to identify any filespec passed :::

'::: work with BMP, GIF, JPG and PNG files. :::
'::: Based on ideas presented by David Crowell :::
'strFlnm => Filespec of file to read
'lngWidth => width of image
'lngHeight => height of image '
'lngDepth => color depth (in number of colors)
'strImageType => type of image (e.g. GIF, BMP, etc.)
'The routine returns FALSE if the file was not recognized as a valid image type, and TRUE if it is 'probably' a valid image file.
