Pixelated Product's Images

[Digital360Europe]

I am a newbie to Prestashop and I would like your help. 😕

On the site where I develop Prestashop 1.7.6.2, I have used a Module that compressed all the photos of the products to provide better loading time. 
Unforulnaly the result is very bad and the images are pixelated.

I wonder if there is a way to restore the product's images to their original resolution.

I have checked from my FTP and the original photos exist.🙏

did you clear the cache after resizing? That might be a reason for pixelated images.  However, if you have the originals you can go into images and let prestashop redo your images.

Thank you very much for your help.☺️ Do I have to regenarate all images and select to delete previous? I am afraid loosing them because I have done a lot of work with 5000 products...

Regenerate images and remove the previous ones:

If you have chosen a webp format compression format, they will still remain on FTP.
You won't be able to regenerate 5000 images with Prestashop.
You will be hit with an expiration error of max_execution_time.

[Digital360Europe]

Yes, the format was webp. And now I try to regenerate product images but not all together at once.

First I have tried the "large_default"but no luck. I have the same resolution and I don't know what to do....

Here is a script that removes all webp images and all thumbnail images.
Does not delete the original image.

If the script finishes with an error (time runs out), no matter, you can run it again.
Checks if there is an image, if any, deletes it, otherwise it continues.

Save the script as eg delete-image.php
Save this script to the Prestashop main directory.

 

If you just want to test the script, just 3x comment on unlink.

//unlink($imag....

 

I recommend backing up the ./img/p folder !!!

<?php
  ini_set('display_errors', 1);
  ini_set('display_startup_errors', 1);
  error_reporting(E_ALL);

  include(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'config' . DIRECTORY_SEPARATOR . 'config.inc.php');
  include(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'config' . DIRECTORY_SEPARATOR . 'settings.inc.php');
  
  $images_path = '';
  $get_images = Db::getInstance()->ExecuteS('SELECT * FROM '._DB_PREFIX_.'image ORDER BY id_product ASC;');
  $get_images_type = Db::getInstance()->ExecuteS('SELECT * FROM '._DB_PREFIX_.'image_type ORDER BY id_image_type ASC;');
  
  foreach ($get_images as $get_image) {
      $image = new Image($get_image['id_image']);
      $image_webp_url = _PS_ROOT_DIR_.'/img/p/'.$image->getExistingImgPath().".webp";
      $images_path .= $image_webp_url."\r\n";
      
      if (file_exists($images_path)) {
          unlink($images_path);
          echo 'deleted image: '.$images_path.'<br />';
      }
      
      foreach ($get_images_type as $get_image_type) {
          $image_jpg_url = _PS_ROOT_DIR_.'/img/p/'.$image->getExistingImgPath().'-'.$get_image_type['name'].".jpg";
          
          if (file_exists($image_jpg_url)) {
              unlink($image_jpg_url);
              echo 'deleted image: '.$image_jpg_url.'<br />';
          }
          
          $image_webp_url = _PS_ROOT_DIR_.'/img/p/'.$image->getExistingImgPath().'-'.$get_image_type['name'].".webp";
          
          if (file_exists($image_webp_url)) {
              unlink($image_webp_url);
              echo 'deleted image: '.$image_webp_url.'<br />';
          }
      } 
  }
  
  echo 'Done';
  
  
  

 

Then just write a script that regenerates the images. But I will not write here anymore.
It's laborious.

I am finishing up a module that will run without restriction timeout.

[Digital360Europe]

Hello! I almost have done! I follow your instructions and I am almost there...

 

You should have told me from the beginning to try it.

Even in a trial version it would have saved me from many hours of coding.🥴

Now I am testing my module and seems that working...🙏
