Empty IPTC fields are being displayed

Originally posted in http://www.pragmamx.org/Forum-topic-23114.html in German, here's the rough translation:

small request. 
I have IPTC display enabled. Only the field "Copyright" is being populated.
However, empty fields are being displayed. I have to workaround this by applying the changes suggested below to dsiplayimage.php each time I have to update:

Original code:
starting at line 191:   

Code Select Expand

if (isset($iptc) && is_array($iptc)) {
      array_walk($iptc, 'sanitize_data');
        if (isset($iptc['Title'])) $info[$lang_picinfo['iptcTitle']] = $iptc['Title'];
        if (isset($iptc['Copyright'])) $info[$lang_picinfo['iptcCopyright']] = $iptc['Copyright'];
        if (!empty($iptc['Keywords'])) $info[$lang_picinfo['iptcKeywords']] = implode(' ',$iptc['Keywords']);
        if (isset($iptc['Category'])) $info[$lang_picinfo['iptcCategory']] = $iptc['Category'];
        if (!empty($iptc['SubCategories'])) $info[$lang_picinfo['iptcSubCategories']] = implode(' ',$iptc['SubCategories']);
    }
   
Better would be:

Code Select Expand

if (isset($iptc) && is_array($iptc)) {
      array_walk($iptc, 'sanitize_data');
        if (!empty($iptc['Title'])) $info[$lang_picinfo['iptcTitle']] = $iptc['Title'];
        if (!empty($iptc['Copyright'])) $info[$lang_picinfo['iptcCopyright']] = $iptc['Copyright'];
        if (!empty($iptc['Keywords'])) $info[$lang_picinfo['iptcKeywords']] = implode(' ',$iptc['Keywords']);
        if (!empty($iptc['Category'])) $info[$lang_picinfo['iptcCategory']] = $iptc['Category'];
        if (!empty($iptc['SubCategories'])) $info[$lang_picinfo['iptcSubCategories']] = implode(' ',$iptc['SubCategories']);
    }

Could you please add this to the next version?
