Division by zero bug if a image fresh uploaded/saved and viewed - quick solution to fix

Find the lines; I think 2795 in module file.

    // We use the if to avoid division by zero if the image path is wrong
    $img = image_get_info($node->gallitems[$pid]->ppath);
    if (count($img)) { // <<< Replace this
  
      ...
  
    }
    else {
      $direction = '';
    }

Replacement:

    // We use the if to avoid division by zero if the image path is wrong
    $img = image_get_info($node->gallitems[$pid]->ppath);
    $direction = '';
    if ($img && !empty($img['extension'])) { // <<< Replacement
  
      ...
  
    }
//    else {
//      $direction = '';
//    }

Note: You can remove else an initiate $direction before if.
