The data return by exif_thumbnail php function has a zero strlentgh. To cross-check : command line exiftool sees exif preview and thumbnail data. So there is a problem. I can provide two sample pictures. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72735&edit=1
