I'm putting one up on my web site at http://www.astrofoto.org/people/roland/bug.php. The image being probed can be loaded from the URL http://www.astrofoto.org/people/roland/20020716-1.05.jpg ------------------------------------------------------------------------ [2002-09-03 12:05:51] roland@astrofoto.org I have a JPEG (*not* from a digital camera) to which I have added a comment block using wrjpegcom. rdjepgcom confirms that the comment is correct in the file. The length of the comment is about 345 characters. When I read the comment back from PHP using read_exif_data, the length is truncated at 198 characters. Note that JPEG comment blocks can be up to 64k(!). The comment in question is all text, no ASCII nulls, so I'm assuming this truncation is happening inside PHP. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19210&edit=1
