Which particular keywords are read? PS uses quite a large set including some custom ones based on manufacturer. In CPG we only read certain parts of the IPTC data as you can see from the code below. We should for CPG1.6 review this list. At least 1 field is depreciated.
function get_IPTC($filename) {
$IPTC_data=array();
$size = GetImageSize ($filename, $info);
if (isset($info["APP13"])) {
$iptc = iptcparse($info["APP13"]);
if (is_array($iptc)) {
$IPTC_data=array( "Title" => $iptc["2#005"][0], # Max 65 octets, non-repeatable, alphanumeric
