You can specify which Image field to use and which fields are editable from the managed Model $imageField (string): The name of the image field to use (should have 'ID' at the end: If your relation is set has 'MyImage' => 'Image', the parameter should be 'MyImageID') $editableFields (array): list of db fields name as string that will be editable like: array('myTextField', 'myVarcharField', 'myEnumField')

Sample Files

Page Model

	class Page extends SiteTree {

		public static $db = array(
		);

		public static $has_many = array(
				'Visuals' => 'Visual'
		);

		public function getCMSFields() {
			$fields = parent::getCMSFields();

			$config = GridFieldConfig_RelationEditor::create();	
			$config->addComponent(new GridFieldBulkImageUpload());		
			$f = new GridField('Visuals', 'Case Study Visuals', $this->Visuals(), $config);
			$fields->addFieldToTab('Root.Visuals', $f);

			return $fields;
		}

	}

Visual Model

('Image', 'Type', 'Title' and 'Embed' Fields will be picked up automatically by the component)

	class Visual extends DataObject
	{
		public static $db = array(
				'Type' => "Enum('Image,Embed','Image')",
				'Title' => 'Text',
				'Embed' => 'HTMLText'
		);

		public static $has_one = array(
				'Page' => 'Page',
				'Image' => 'Image'
		);

		public function getCMSFields() {
			$fields = new FieldList();

			$fields->push( new DropdownField(
				'Type',
				'Type of visual',
				singleton('Visual')->dbObject('Type')->enumValues()
			));

			$fields->push( new TextField('Title', 'Title and Caption for images (useful for SEO)') );
			$fields->push( new TextareaField('Embed', 'HTML Embed code') );		

			$f = new UploadField('Image', 'Image file');				
			$fields->push($f);

			return $fields;
		}
	}

Notes

The HTML form fields for each editable fields are taken from the Model's getCMSFields() method
Only (HTML)Text/Varchar and Enum fields are picked up by the automatic config for now

@TODO

Add option to specify upload folder
Add individual actions for each upload (update + cancel)
Styles: fade progress bar back to blue once updated
Styles: add .loading class to buttons when saving/canceling
Handle and display errors better for: creation, update, cancel
Make it work not only for images -> might need to rename this component then?
