How to fix the issue: Product images missing in backend but not in frontend

June 22, 2012  |  28 Comments  |  by Raj (MagePsycho)  |  Latest, Magento

Introduction

Recently i have to fix a strange issue for one of my client. Issue was that product images were missing from ‘Images’ tab of product edit form (as depicted below), though they were displaying fine in the frontend.

Missing Product Images In Backend

After going through the table relationship for catalog product images (as shown below), it was found that required rows were missing in table ‘catalog_product_entity_media_gallery’. Note that table ‘catalog_product_entity_media_gallery_value’ is not necessary unless you want to sort or label the product images.

Schema For Product Images

By inspecting the html code of Images tab of product edit form via firebug, it was seen that ‘value’ attribute had empty json:

<input type="hidden" value="[]" name="product[media_gallery][images]" id="media_gallery_content_save">

Further Debugging:
Using template path hints extension for admin: Easy Template Path Hints, it was found that the responsible template and block class were: ‘app/design/adminhtml/default/default/template/catalog/product/helper/gallery.phtml’ and ‘Mage_Adminhtml_Block_Catalog_Product_Helper_Form_Gallery_Content’ respectively.

Looking at the block class and .phtml code it was found that Input element has empty json because of Mage_Adminhtml_Block_Catalog_Product_Helper_Form_Gallery_Content::getImagesJson() method.

When populated the images from table ‘catalog_product_entity_varchar’ to ‘catalog_product_entity_media_gallery’ for those products, products images were seen at the backend(refer to the code below for more info).
Here goes the steps for fixing:

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');

3> Open your browser and run the following url:

http://your-magento-url/update_missing_images.php

4> That’s all. Try to browse the Images tab, now you will see those missing images.

Hope this helps somebody!

    I’m trying this solution but it is not working. When I run the php file in the browser, it is giving me a 500 internal server error.

      For 500 internal server error, be sure to check error-log. You can get more info about the cause.

  • Vincent

    So when for the CSV file, do I just have one column with SKU and then list the SKUs of the products that have missing images? It still isn’t working. I’m trying this method on images that I uploaded several weeks ago.

  • Paul

    Thanks for this fix! I’m pretty sure it’ll work, but right now it doesn’t appear to. :( Maybe I’m misunderstanding the use??

    Our client imports products (as a csv) with the image paths and uploads the images to the correct path. As far as I know everything works fine when they do that. HOWEVER, if they manually update a product, the images get reset to no_selection.

    When I run this code, I get all of the skus with the Success message, but nothing appears to be updated in the catalog_product_entity_varchar table. Any ideas what it could be??

  • devonshire

    this is the closest post I’ve found to solving my problem. Do you know of a way I can fix this on a global level – so that whenever I import I do not have to run this fix again? Thanks

    I had this problem and was close to using your solution. However, with a little more checking, I realised that media_attribute_id, media_image, media_position and media_is_disabled were all not set. After re-uploading products
    (just sku plus the aforementioned columns) the issue was fixed, with images appearing in the backend and frontend successfully.

    media_image (path to your main image)
    media_attribute_id (for me was 88, get this from the table catalog_product_entity_media_gallery – it may vary for different versions.
    media_postition (1)
    media_is_disabled (0)

    Not sure if that will solve everyone’s problem, but it worked for me, without doing any of the ‘scary’ stuff above. I’m on 1.7.

      Thanks a lot Nathan its really great..worked for for me perfectly…

      • P

        Thanks Nathan. I did a lot of research for the answer to be so simple. Wish I had found your response a few hours ago.

  • Claire

    Not sure if this applies to your situation, but I have just installed 1.7.0.2 and tried to import a CSV with product with multiple images which I had exported from a previous 1.6.x installation. I was tearing my hair out as it was only showing one image on the front end, and no images at all on the backend. To resolve this I created a dummy product in the new install, added multiple images, exported the products out, and looked in the CSV file for the _media_attribute_id column. The number in here was 88 for the new install, but 82 for the export from the old install, so I simply updated the number, reimported the CSV from the old install again, and voila, it worked perfectly.

      We really struggled with this too and had seen the sql code to run but saw your post and decided to give it a go first and it worked! We exported from EE into CE 1.7 and the media_attribute_id changed as per yours – from 82 to 88. So we changed this on the import and ran it again. Images now show on the front end and in admin as you can see on LansonRunning.com.

  • Martin

    Thanks, Nathan! Works like a charm. However, you left the underscore off the field names. Fields should be:

    sku
    _media_image (path to your main image)
    _media_attribute_id (for me was 88, get this from the table catalog_product_entity_media_gallery – it may vary for different versions.
    _media_postition (1)
    _media_is_disabled (0)

    Run it with just these fields to fix products that were previously uploaded. Add these fields to any future product imports to avoid the missing product image in the backend.

    Thanks It works!!!!!!! Save my day

    Thanks Nathan,

    It worked for me

  • http://www.tansarc.nl Finn

    Thanks for posting this solution. I got half way figuring out what was going on when I decided to Google. Luckily this post was with the first few results pointing me to the cause of the problem. Thanks Claire for mentioning the possible difference in _media_attribute_id, that got my import conversion script generating working import CSV again by just updating the id :D

  • http://www.stylishweddingfavors.com Debra Hogan

    After trying all kinds of suggested solutions, I tried yours. Thank you! This is the only one I found that really works. So many of the others mention media_attribute_id which no longer exists as an attribute in 1.7.0.2 by default. It is now called media_gallery, but even then the other solutions did not work.

  • http://buysomegear.com Jim

    Totally worked on 1.7.02. Just had to reindex afterwards, and BAM! Images on the backend. I’m gonna play around with Nathan’s idea too – I suspect it will work, but I tried it earlier with a failure…although I may not have reindexed afterwards?

  • Robert Bavington

    Thank you so much for this fix, I was searching hi and low for a solution for this problem and I couldn’t work out why my images were not showing in the back end. This is an excellent example of community support!

  • Sangay Tenzin

    Thank you very much for this. Wish I fount this post earlier. I have already spent one day trying to get the images on the backend after import : (

  • FrankLuska

    Thank You, Thank You, Thank You!

  • Robert Howell

    you are the man.. I managed to import all my products and the images where every where but in the product description for the admin, so if I edited the product the image would disappear from the losting as it was not there.. your mod worked perfect! I’m using Magneto CE 1.8

  • Daryl

    You beauty!

  • rrroulio57

    ouawww. 2 days with my bug. the answer here. Thanks!!!

  • Pierre

    Thanks, perfect.
    Want to update all SKU :

    $productsCollection = Mage::getModel(‘catalog/product’)->getCollection();
    foreach($productsCollection as $product) {
    $sku = $product->getSku();
