Magento – magento image filename auto renaming

Place the image under media/import then in the CSV use /p1.jpg - there is no need for the extra /product sub-directory.

I have fixed the issue Product images missing in backend and visible in front end. The problem was missing relations between the tables related to to catalog product. I have fixed the issue by following this tutorial:

http://www.blog.magepsycho.com/how-to-fix-the-issue-product-images-missing-in-backend-but-not-in-frontend/

Steps:

1> Prepare CSV file(update_missing_images.csv) with only one field: sku and upload to the root of Magento installation. Note: This will contain the sku of those products whose images are missing at the backend.

2> Create a file: update_missing_images.php and upload to the root of magento installation and paste the following code:

<?php
/**
 * @author      MagePsycho <info@magepsycho.com>
 * @website     http://www.magepsycho.com
 * @category    Export / Import
 */
$mageFilename = 'app/Mage.php';
require_once $mageFilename;
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
umask(0);
Mage::app('admin');
Mage::register('isSecureArea', 1);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

set_time_limit(0);
ini_set('memory_limit','1024M');
