>         return $this->smarty->display($this->pathToTemplates . '/' . $view);

>         // Check if teh file exists on the FS

>             $image_file_name = $this->conf['uploadFolder'].$image;
>             }
>         else {               
>             $image_file_name = $this->conf['noImage'];
>         }           
>         $cObj -> data['tmpfile'] = $image_file_name;
>         $TSconf['titleText'] = $titleText;
>         $TSconf['altText'] = $altText;
>            
>         // Try to render the image in it's origional state as supported 
> my IM
>         // IF GIFBUILDER was enable for this image config
>         if ($TSconf['file.']['format'] && $TSconf['file'] == 'GIFBUILDER') {
>             $off = strtolower($pInfo['extension']);
>             switch (strtolower($pInfo['extension'])) {
>                 case 'gif':
>                     $TSconf['file.']['format'] = 'gif';
>                     break;
>                 case 'png':
>                     $TSconf['file.']['format'] = 'png';

>         }
>         return $cObj -> IMAGE($TSconf);

Hi Ries,

there are several possible ways and what you write looks quite OK for
me. I can imagine that you will find some or other better trick by time,
but you got started and you experienced the basic principles.

It is right to do as few as possible in the controller. It should mainly
controll the chain of workwflow of the different objects.
