Can you make such an image available for download?

You can download the cover of my portfolio : www.gillesvds.fr

Thanks. I've downloaded the image and this script:

    <?php
    $data = array_intersect_key(
        exif_read_data('./69854.jpg'),
        ['Copyright' => null, 'Make' => null, 'Model' => null]
    );
    var_dump($data);
    
produces:

    array(3) {
      ["Make"]=>
      string(1) "☺"
      ["Model"]=>
      NULL
      ["Copyright"]=>
      string(10) "llesvds.fr"
    }

Apparently, this is nonsense, but Adobe Lightroom concentrates not
on classic EXIF, but rather on IPTC metadata in XMP format[1].
IPTC metadata are not subject of exif_read_data(), but rather of
iptcparse(). Using the example from the iptcparse() man page[2]
yields somewhat better results, but still not what is desired. I
believe, however, that this is not a bug in iptcparse(), because
the documentation states:

| Parse a binary IPTC block into single tags.

XMP format is, however, not binary, but an application of XML.

Therefore I'm switching this ticket to feature request.

You may consider to look for a PHP library which can read and
parse IPTC/XMP metadata.
