   Dear All,

   I would like to add a resize feature for mobile devices, but I can't find any complete example how to implement it using PHP classes developed by Axel.
   What I would like to have is a resize and caching of resized images the same way it's done in nggSinglePicture() function, but I'm a bit puzzled on how to apply filters (probably 'ngg_image_object'), could someone please point me on how to use it, or PHP files to closely look at?

   That's part of my code:

   $results = $wpdb->get_results("SELECT * FROM $wpdb->nggpictures" . $sql_where . " ORDER BY " . $sql_order . $sql_limit);
   ...
   foreach($results as $result)
         {
           $gallery = $wpdb->get_row("SELECT * FROM $wpdb->nggallery WHERE gid = '" . $result->galleryid . "'");
           foreach($gallery as $key => $value)
           {
               $result->$key = $value;
           }
           $image = new nggImage($result);
           //output in div...
           ...
           <img src=\"" . $image->imageURL . "\"">
           ...
         }
   ...

   p/s/ I noticed that that function is used for DB query

   $picturelist = nggdb::get_gallery($galleryID, $ngg_options['galSort'], $ngg_options['galSortDir']);

   So I guess my two DB queries can be replaced by this one?

   Sincerely yours,
   Denis.

   Reading image.php file, i noticed "cached_singlepic_file",
   I guess that's exactly what I need to use:

   $image->cached_singlepic_file($width, $height,'');

   ?

   So, is it safe to do it for some 15-25 pictures? I don't plan to change sizes often, basically I would visit page once myself to initiate mobile-version images construction, and would not change the size later.

   Any downsides of that idea?

   Finally, I come with a temporary solution to use thumbnails for mobile devices, so I have something like:

   $is_mob = 0;
   if ( function_exists( 'bnc_wptouch_is_mobile' ) && bnc_wptouch_is_mobile()  ) {
       $is_mob = 1;
       }
   ...
   if ($is_mob ==0) {
       $curURL = $image->imageURL;
   } else {
       $curURL = $image->thumbURL;
   }
