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

Introduction

Recently I have to fix a strange issue for one of my clients. The 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.

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 the table ‘catalog_product_entity_media_gallery_value’ is not necessary unless you want to sort or label the 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 go 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

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!

  1. 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.

  2. 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.

  3. Thanks for this fix! I’m pretty sure it’ll work, but right now it doesn’t appear to. ๐Ÿ™ 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??

  4. 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

  5. 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.

  6. 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.

  7. 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 โ€“ 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.

  8. 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 ๐Ÿ˜€

  9. 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.

  10. 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?

  11. 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!

  12. 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 : (

  13. 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

  14. Thanks, perfect.
    Want to update all SKU :

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

    • Hey Pierre, You posted a year ago. But any chance you remember where exactly this code belongs? I would like to update all the skus instead of the csv file skus

  15. Thank you Very MUCH!!!! I lost about a whole day to try to find a solution and Boom i found yours!! Thank you , you saved me a lot of time!!! Cheers Tested on Magento 1.9

  16. Parse error: syntax error, unexpected ‘$mageFilename’ (T_VARIABLE) in /home/magento/public_html/update_missing_images.php on line 6

  17. Still works great over two years after original post. I slightly modified it to run using php cli to keep the script more secure. better to keep utility scripts out of the public web root in my opinion. Thanks for the great tool!

  18. First off: thanks for the script, works great on Magento CE 1.8.1.0. I had the problem not knowing which products were affected/messed up, what was the cause of the error. It turned out that it only effected products beeing imported, that did NOT have the column “_media_image” set. Be sure to add the images to the “_media_image” column before setting the “image”, “small_image” and “thumbnail”. Another quick note: be sure to add a heading “sku” to your csv-file.

  19. hi I’m getting the following error mage_mage_catalog_product_entity_media_gallery’
    doesn’t exist on each image update my tables are preceeded with mage_ so
    mage_catalog_product_entity_media_gallery does exist. What do i need to change to get your file to work? Thanks

  20. Good Work Raj,,

    Code is working fine. This solution contains few things that are new for me, I wasn’t aware of.
    I use FME Photo Gallery Magento extension ( http://goo.gl/6Ufp6M ) to manage and display product photos anywhere in the website.

  21. Magento 1.9.2 doesnt work for me, it only loads blank page with thats all and images dont get updated. Any suggestions?
