Thanks,

public function saveAction()
{
/* START: Handle the max images per product */
$data = $this->getRequest()->getPost();
$images = Mage::helper('core')->jsonDecode($data['product']['media_gallery']['images']);
if($totalImages = count($images)) {
$maxPhotoPerProduct = 5;
if($totalImages > $maxPhotoPerProduct) {
Mage::getSingleton('core/session')->addError($this->__('Max. number of images per product reached, extra images have been removed'));
}
$_allowedImages = array_slice($images, 0, $maxPhotoPerProduct);
//Return the allowed images back to the $_POST
$_POST['product']['media_gallery']['images'] = Mage::helper('core')->jsonEncode($_allowedImages);
}
/* END: Handle the max images per product */
//Zend_Debug::dump(Mage::helper('core')->jsonDecode($_POST['product']['media_gallery']['images'])); exit;
//Run standard saveAction()
parent::saveAction();
}
Note that code above is from my Mycompany_Mymodule_Adminhtml_Catalog_ProductController class located in the “app/code/local/Mycompany/Mymodule/controllers/Adminhtml/Catalog/ProductController.php” file.
Meaning I overwrote the default “app/code/core/Mage/Adminhtml/controllers/Catalog/ProductController.php” controller by using the syntax shown below in Mymodule config.xml file.
</config>
...
<admin>
<routers>
<adminhtml>
<args>
<modules>
<sintax before="Mage_Adminhtml">Mycompany_Mymodule_Adminhtml</sintax>
</modules>
</args>
</adminhtml>
</routers>
</admin>
...
</config>
