Processing photos in a loop:
Took me longer than I wanted.

Docs are missing an entry for image_lib->initialize(), and that is the key.

The information is there, but you have to read the page slowly and carefully, like a gripping novel. I prefer griping. Which is not novel.

Just in case another has the same issue, here is what worked for me:

load lib
begin loop
clear
set options
initialize
invoke method
end loop

Code:
// resize all pics in a folder (replace existing). We want a max size of 10K per thumb

    function rethumb()

    {

        $picpath = $this->config->item('base_dir') . '/my/file/videos/image';

        $this->load->library('image_lib');

        $aFiles=$this->get_files($picpath);

        foreach($aFiles AS $fn)

        {

                $fn = $picpath . $fn;

                $filesize = filesize($fn);

                if ( ($filesize >0) AND ($filesize < 10240) )

                {

                  continue;

                }

                echo "<BR>$fn";

                $this->image_lib->clear();

                $config['image_library']    = 'gd';

                $config['create_thumb']        = TRUE;

                $config['maintain_ratio']    = TRUE;

                $config['width']                    = 150;

                $config['height']                    = 150;

                $config['master_dim']            = 'width';

                $config['thumb_marker']        = '';

                $config['source_image']        = $fn;

                $this->image_lib->initialize($config);

                if ( ! $this->image_lib->resize() )

                {

                     echo '<BR><B>' . $this->image_lib->display_errors() . '</B>';

                }

        }

     }

PS: If you are using phpFox, take a look at your video image folder. Some of them thumbnails are .5MB !
