Hi, I have tried to run this script by copying in a file with the extension php, than uploading it to my magento installation root and running it by www.mysite.de/image-clear.php, but nothing happened. Any ideas what I did wrong? Thanks in advance.

Working perfectly and really fast, it remove 12,5GB in just few seconds. Answering mittelgelb, you have to upload the script to the /shell folder and then execute it from the command line: something like that:
/usr/bin/php shell_delete_unused_images.php

Thanks for the script!

If you have a strange site setup where the entity_type_id for products isn't "4", this script will return 0 results for images in the database. In turn, that will try and delete every single product image uploaded, which is not ideal.

The following modified script (taken from @manueltoniato 's changes) will check for the correct entity_type_id and use that in the following select query:

Step 1:
Check directory size before execution
du -s
Copy Mr. dajve code and create a file in
vi shell/shell_delete_unused_images.php

Step 3:
Execute file
php shell/shell_delete_unused_images.php

Step 4:
Check directory size after execution
du -s

I would go for du -sh to see the size in human readable form.

Hi, there is a way to also delete the files, since it only does not show them inside the products, the files are within the means?

thanks!

Hi @tarikuli can you please tell me how can i active the debug mode. i just want to check how many images to delete.

Thanks.

Beautiful! If I understand correctly, this script will delete the images that are no longer linked to no product ... That is, if I have only "disabled" products, in this case the images will not be deleted? It is important to keep them for me ... Also how do I run the script? Load in the foot and what do I type in the URL? Thank you

Hi @Ang90, this is a CLI script you must launch from the command line.
Pay attention this is a script for Magento 1.
Take users' comments int account because I didn't maintain the script.

Because I want to know, wether it is debug or dryrun, I added some echo:

Since my last post in 2016 I discovered the following extension for Magento 1/OpenMage: https://github.com/fballiano/openmage-image-cleaner.

This is by far the most advanced functional extension which has a lot of useful features. For a while I used ImaClean, but I removed it in favor of the extension mentioned above. It is installed in production and offers a complete visual control over what is deleted. It is not limited only to product pictures, but can also solve other places where could be orphaned images.
