Magento – Product images use default value

gallerymagento-1.7scope

After changing some data for product inside particular store view, "Label" and "Sort order" fields no longer obtain values from Default Values scope if those values are changed.

I will illustrate the example:

This is default scope view:
Then I change Store View into English and change any data (product name for example).
I switch again to Default Values scope and change in images Sort Order.
But English view don't obtain this updated value.

Why there is no option "Use Default Value" for image Label and Sort Order fields? There is just for Base Image, Small Image, … Is there any way to solve this problem? Or do we need to make any changes twice just because we changed product name?

The scope of the attribute media_gallery is is_global = 1 which means it is global. You can try to change the scope, I don't know what the side effects are:

Just add to your sql update script:

$this->updateAttribute(
    Mage_Catalog_Model_Product::ENTITY,
    'media_gallery',
    'is_global',
    Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE
);

Good luck.

Not sure if this a solution to your problem, but it can be a hint in the right direction.
You can specify a custom element rendered in any one of your form tabs like this (the example is from the catalog module):

protected function _prepareLayout()
{
    Varien_Data_Form::setElementRenderer(
        $this->getLayout()->createBlock('adminhtml/widget_form_renderer_element')
    );
    Varien_Data_Form::setFieldsetRenderer(
        $this->getLayout()->createBlock('adminhtml/widget_form_renderer_fieldset')
    );
    Varien_Data_Form::setFieldsetElementRenderer(
        $this->getLayout()->createBlock('adminhtml/catalog_form_renderer_fieldset_element')
    );
}

The last method sets the element renderer block. You can try to use that but I think you will get some errors because that is destined for EAV entities.
You can create a block that extends Mage_Adminhtml_Block_Catalog_Form_Renderer_Fieldset_Element and add a custom template to it similar to catalog/form/renderer/fieldset/element.phtml where you can add your checkboxes or anything else.

How to Find if Product Attribute is Set to Use Default Value

Let's say that $product is the instance of your product loaded in a specific store.
You can check this

$basePrice = $product->getAttributeDefaultValue('price');
if ($basePrice === false) {
     //Use default values is checked
} else {
    //$basePrice is the price in the default values.
}

Unfortunately this works only if you call load on the product model, not if you get the product from a collection.

I mean, this works

$product = Mage::getModel('catalog/product')->setStoreId($storeId)->load($productId);
var_dump($product->getAttributeDefaultValue('price'));

This will produce a value if the price is different on the website that contains the store view with the id $storeId and it will produce false if "Use default values" is checked.

This won't work.

$collection = Mage::getModel('catalog/product')->setStorId($storeId)->getCollection()
    ->addAttributeToSelect('entity_id', array('eq' => $productId));
foreach ($collection as $product) {
    var_dump($product->getAttributeDefaultValue('price'));
}

This will always produce false.
