OK...not sure if i'm providing enough information or not, but hopefully someone can help me. When I upload images to a directory, the default permissions are set to 600 on the files themselves. The directory has 777 permissions. I want to make my images readable and give them either 666 or 644 permisssion. Either would work. I suppose I need to somehow chmod the image files during upload or just after. Here is my code snippet that handles the image upload. I'm just not sure how to implement the needed change.

/***start****/
if ( $_FILES['bgimg']['name'] && !$_POST['bgdel'] )
    {

          if ( strlen($custom_arr['BackgroundFilename']) && file_exists($dir['profileBackground'] . $custom_arr['BackgroundFilename']) && is_file($dir['profileBackground'] . $custom_arr['BackgroundFilename']) )
              @unlink($dir['profileBackground'] . $custom_arr['BackgroundFilename']);

      srand(time());
      $pic_name = $ID . '_bg_' . rand(100, 999);
      
                  if ( !is_int($ext = moveUploadedImage( $_FILES, 'bgimg', $dir['profileBackground'] . $pic_name, '',false) ) )
                  
                  {
                  
                      if ( !$record_created )
                      {
                          $query = "INSERT INTO ProfilesSettings (`IDMember`, `BackgroundFilename` ) VALUES ( '$ID', '$pic_name$ext' )";
                              $record_created = 'ok';
                      }
                      else
                      {
                          $query = "UPDATE ProfilesSettings SET `BackgroundFilename` = '$pic_name$ext', `Status` = 'Approval' WHERE `IDMember` = '$ID'";
                        }
                      $res = db_res( $query );

                  }

    }
    else if ( $_POST['bgdel'] )
    {

        if ( $custom_arr['BackgroundFilename'] )
            {
                if (file_exists($dir['profileBackground'] . $custom_arr['BackgroundFilename'])) unlink($dir['profileBackground'] . $custom_arr['BackgroundFilename']);

                      $query = "UPDATE ProfilesSettings SET `BackgroundFilename` = '' WHERE `IDMember` = '$ID'";
                      $res = db_res( $query );
                  }

    }

just use

chmod("path/to/uploaded/image/image.ext",0777);

you need to put the leading 0 in front of the permission
