No, I can't. I've got some images, with exif information in the DB. I'm now generating thumbnails for them, and also storing those in the DB. No files at all, and therefore I can't read exif data for the thumbnails. As I said I've solved the problem by writing a temporary file and reading exif from that. Not pretty or efficient, but it works. //Niels -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
