Because PHP is running on our server without a whole lot of privileges, it cannot chmod the images that the FTP user uploads for importing. It is able to successfully create the album, move the images, and have the album display properly (as far as I can tell)--so everything seems to work alright anyways. After the album is created though, it outputs a batch of warnings that chmod didn't work. Is this chmod server-dependent (what I mean is, the gallery is fine on our server without this chmod, but may not be on someone elses)? Maybe instead of having the script attempt to chmod, the install could set a configuration option (which could later be changed) to say whether scripts should try to chmod. Or at least, the script could check every time if it is able to chmod and report after the operation something like: "Album was created successfully but I was unable to chmod the image files, please verify that the album displays correctly."
