changing iptc data fields while uploadin

[gos1]

hi
I want my coppermine to use headline field instead of keywords while displaying in the site. 
Which file should I modify? I mean which file inserts the image data in the database ?

i am now modifying the displayimage.php file and find the iptc data part.

Code Select Expand


  if ($CONFIG['read_iptc_data']) $iptc = get_IPTC($path_to_pic); //echo "IPTC on";



    if (isset($iptc) && is_array($iptc)) {

if(is_array($iptc['Keywords'])) { $ikw=implode(",", $iptc['Keywords']); } else { $ikw=$iptc['Keywords']; }

require_once("ConvertCharset.class.php");

$NewEncoding = new ConvertCharset;

        if (isset($iptc['Title'])) $info[$lang_picinfo['iptcTitle']] =  $NewEncoding->Convert(trim($iptc['Title']), "x-mac-roman", "utf-8", 0);

        if (isset($iptc['Copyright'])) $info[$lang_picinfo['iptcCopyright']] = $NewEncoding->Convert(trim($iptc['Copyright']), "x-mac-roman", "utf-8", 0);

        if (isset($iptc['Keywords'])) $info[$lang_picinfo['iptcKeywords']] = $NewEncoding->Convert(trim($ikw), "x-mac-roman", "utf-8", 0);

        if (isset($iptc['Category'])) $info[$lang_picinfo['iptcCategory']] = $NewEncoding->Convert(trim($iptc['Category']), "x-mac-roman", "utf-8", 0);

        if (isset($iptc['SubCategories'])) $info[$lang_picinfo['iptcSubCategories']] = $NewEncoding->Convert(trim($iptc['SubCategories']), "x-mac-roman", "utf-8", 0);
       
        if (isset($iptc['Headline'])) $info[$lang_picinfo['iptcHeadline']] = $NewEncoding->Convert(trim($iptc['Headline']), "x-mac-roman", "utf-8", 0);

    }




I dont know if it is right but added the Headline part myself. Now cannot understand the logic between the data fetched from iptc data and displaying it to the screen. How Can I manage that ? I want the Headline part to be echoed  in the screen as the file description. And Also I want the headline part to be inserted into the database instead of keyword. Is there a way to do that what should I change and Am I in the right place.._?
