I've got FileDataObjectManager set up and working ok but I want to use ImageDataObjectManager. I'm following the instructions at http://doc.silverstripe.org/doku.php?id=modules:dataobjectmanager&s=imagedataobjectmanager but the instructions for ImageDataObjectManager as follows:

"The ImageDataObjectManager takes the same arguments and configuration as a FileDataObjectManager. The only difference is that its only allowed file classes are Image or subclasses thereof"

...don't mean much to me as I'm not a developer.

Can any one help with how to set this up or provide some example code?

Thanks

Thanks for the quick reply?
Where can I find these docs?

I'm already looking at that, I've set up the file manager and it's working ok but I just don't know which bits of code I need to change and what I need to replace with to make the ImageDataObjectManager work?

Thanks again

Thanks again for your help, I've changed the bits I think shoudl be chanegd as per yoru instructions but the resources tab is just showing blank in the cms, ie the tab is there but has nothing in it. My code is as follows, I'm sure I'm missing something:

class ResourcePage extends Page
{
   static $has_many = array (
      'Resources' => 'Resource'
   );
   
   public function getCMSFields()
   {
      $f = parent::getCMSFields();
      $manager = new ImageDataObjectManager(
         $this, // Controller
         'Resources', // Source name
         'Resource', // Source class
         'Attachment', // File name on DataObject
         array(
            'Name' => 'Name',
            'Description' => 'Description',
            'Category' => 'Category'
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause
      );
$f->addFieldToTab("Root.Content.Resources",$manager);
return $f;
}

}

AND

class Resource extends DataObject
{
   static $db = array (
      'Name' => 'Text',
      'Description' => 'Text',
      'Category' => "Enum('2009, Transitional-Spaces, Brighton-Bands')"
   );
   
   static $has_one = array (
      'Attachment' => 'Image',
      'ResourcePage' => 'ResourcePage'
   );
   
   public function getCMSFields_forPopup()
   {
      return new FieldSet(
         new TextField('Name'),
         new TextareaField('Description'),
         new DropdownField('Category','Category', singleton('Resource')->dbObject('Category')->enumValues()),
         new FileIFrameField('Attachment')
      );
   }
}
