Hi All,

I'm creating a basic gallery for a site, where the admin of the site just uploads images into a specific folder, and they're displayed on a page. I don't the site owner to have to do anything else.

I've attempted using the Image.SetWidth to generate thumbnails, that works okay and a resized image is saved in assets which is fine. I then expect it to reuse it, but it doesn't, it regenerates the thumbnail everytime the page is viewed. The test server I'm using is slowing down to a crawl every time I view the page, the final site will be on shared hosting as well, and I don't want this page to interrupt other clients. Is there a way to tell it to look for an already resized version before regenerating thumbnails?

doh, I read through the source code, it was because '?flush=1' was in the URL

Hi StuM,
I'm very new to SS and I have implemented a basic image gallery similiar to your.
It works well and I would like to share my code with you. I don't know if my code is ok.. mabe could be better..


class ApartmentsPage extends Page {
   static $db = array();
   static $has_one = array();

   function Galleria() {
      $object = new stdClass();
      if ($handle = opendir($path)){
         $path = substr($path,3);
         while(false !== ($file = readdir($handle))) {
               $object->$i = File::find($path.$file);
      return $object;


class ApartmentsPage_Controller extends Page_Controller {


<% control Galleria %>
   <span style="float: left;padding: 3px;margin-bottom: 3px;"><a href="$URL">
   <% control CroppedImage(100,100) %>
      <img src="$URL" />
   <% end_control %>
<% end_control %>

I'm "reading" all jpg files inside Assets/Appartamenti/<Page Title>/ , creating the object of the reading result and passing it to the control on the ss template.
Don't know if is ok or not... but it works..

Just learned something new and definitely better:

return DataObject::get("Image", "ClassName <> 'Folder' AND ParentID = (SELECT ID FROM File WHERE ClassName = 'Folder' AND Name = '".$this->Cartella_Immagini."')");
