Image caption

Is there any reasonably easy way for the end user to add a caption to an image inserted through the CMS?

I’m not sure if it is good practice, I’d prefer to extend Image class instead of this, but I didn’t arrive to. This MyImage class allows for a caption that you can switch on or off in templates with <% if ShowImagesTitle %><p>$Legend</p><% end_if %>:


** You haven't been able to extend directly Image and add the boolean field
class MyImage extends DataObject {
   static $db = array (
      'ShowImagesTitle' => 'Boolean',
      'Legend' => 'Text'
   static $has_one = array (
      'Image' => 'Image',
      'Page' => 'Page'
   public function getCMSFields_forPopup()   {
      $myImageField = new ImageField('Image');
      return new FieldSet(
         new TextField('Legend'),
         new CheckboxField('ShowImagesTitle', 'Show legend')

Then in your Page class, or a more specific one:


// Pages can have many images (see MyImage for the other side of the relation)
public static $has_many = array(
   'Images' => 'MyImage'

Then later in getCMSFields() you can use, or not, ImageDataObjectManager (included in DOM module):

// This will add a checkbox on the CMS to switch the legend (Title) on images (function later)
// $fields->addFieldToTab('Root.Content.Images', new CheckboxField('ShowImagesTitle', 'Show Title as legend.'));
$fields->addFieldToTab('Root.Content.Images', new ImageDataObjectManager(
      'Legend' => 'Legend',
      'ShowImagesTitle' => 'Show'

Hope it helps (and that I get corrected with a better way of doing it),
