TIFF files come in two "flavors" "big-endian, and little-endian." If you are using photoshop then you have the option to save using IBM PC or Macintosh "byte order" settings. This determines whether the "header" of the file is at the beginning of the data, or the end. If the PHP code is looking for this in the head, and it's actually in the tail, that could cause a problem. In addition, there can be several locations that Fotostation writes the IPTC metadata, depending on your operating system. If you are on a mac, and using an older version of Fotostation, then it's possible that the IPTC metadata is being written to the "resource fork" of the file, rather than the data fork. If this is the case, then when you upload the raw TIFF file, the resource fork is "stripped" and thus the metadata is gone. I downloaded the file and opened in photoshop and could read the file info (it had the word "test" in both the caption and the keyword fields). You might try seeing what happens if you open the file (after editing in Fotostation) in Photoshop, and resave the TIF using the two different "byte orders" and see if that makes a difference. BTW, I moderate a group that deals with metadata issues, and there may be others that have experienced the problems you are finding that are participating. The group is called Controlled Vocabulary and you can sign up at the bottom of the main page at (http://ControlledVocabulary.com/). Hope that helps.

I checked again, and yes both files have the same IPTC data. I can read it with softares lake Fotostation Pro, but not with the PHP code.

Thank you for your interest in PHP. According to image analysis tools I have here the tiff image does not contain any valid IPTC data. ------------------------------------------------------------------------ [2003-11-21 03:36:16] stephane dot rochon at free dot fr Hello, thanks for your help !
