This is not a bug per-se, but more like a missing feature. The additional image fields not being showed at random image / random cat image
The fix is:
in includes/functions.php find:
$random_image_cache = array();
Insert below:
global $additional_image_fields;
$additional_sql = "";
if (!empty($additional_image_fields)) {
foreach ($additional_image_fields as $key => $val) {
$additional_sql .= ", i.".$key;
}
}
Then find:
$sql = "SELECT DISTINCT i.image_id, i.cat_id, i.user_id, i.image_name, i.image_description, i.image_keywords, i.image_date, i.image_active, i.image_media_file, i.image_thumb_file, i.image_download_url, i.image_allow_comments, i.image_comments, i.image_downloads, i.image_votes, i.image_rating, i.image_hits, c.cat_name".get_user_table_field(", u.", "user_name")."
Replace with:
$sql = "SELECT DISTINCT i.image_id, i.cat_id, i.user_id, i.image_name, i.image_description, i.image_keywords, i.image_date, i.image_active, i.image_media_file, i.image_thumb_file, i.image_download_url, i.image_allow_comments, i.image_comments, i.image_downloads, i.image_votes, i.image_rating, i.image_hits, c.cat_name".get_user_table_field(", u.", "user_name").$additional_sql."
Next find:
$sql = "SELECT i.image_id, i.cat_id, i.user_id, i.image_name, i.image_description, i.image_keywords, i.image_date, i.image_active, i.image_media_file, i.image_thumb_file, i.image_download_url, i.image_allow_comments, i.image_comments, i.image_downloads, i.image_votes, i.image_rating, i.image_hits, c.cat_name".get_user_table_field(", u.", "user_name")."
Replace with:
$sql = "SELECT i.image_id, i.cat_id, i.user_id, i.image_name, i.image_description, i.image_keywords, i.image_date, i.image_active, i.image_media_file, i.image_thumb_file, i.image_download_url, i.image_allow_comments, i.image_comments, i.image_downloads, i.image_votes, i.image_rating, i.image_hits, c.cat_name".get_user_table_field(", u.", "user_name").$additional_sql."
