This post is about How to optimize Prestashop in Search Engine Optimization (SEO) perspective by altering images naming convention.

3) How to name the images

It’s been recognised within SEO generally that file names can have an impact on results. This is reflected too within search engine optimisation for images. Use dashes to separate keywords in the file name, rather than underscores.

This quote is from http://blog.webdistortion.com/2009/03/26/seo-for-images-photography/

In this post we will try to optimize Prestashop search engine result by modify the images name used in Prestashop. We have another post which discuss how to reduce Prestashop size by eliminating some useless images. You can refer to this post to understand how Prestashop generate a lot of images varies from the mini one to large one.

This tips is my answer for Prestashop forum thread How to rename images automatically. We use simple technique to modify Prestashop engine, same technique in our previous post.

#1 Modify AdminImages.php

This file is located at ../prestashop/admin/tabs/AdminImages.php. Following our snippet code from AdminImages.php

/* Regenerate products images */
 $errors = false;
 foreach ($productsImages AS $k => $image)
 {
 if (file_exists(_PS_PROD_IMG_DIR_.$image['id_product'].'-'.$image['id_image'].'.jpg'))

 //modification by gm.computer@yahoo.com
 //http://ardianys.com/
 $product = new Product($image['id_product']);
 $langdefault = Configuration::get('PS_LANG_DEFAULT');
 //end of mod

 foreach ($productsTypes AS $k => $imageType)
 {
 //new code
 $newFile = _PS_PROD_IMG_DIR_.$image['id_product'].'-'.$image['id_image'].'-'.$product->link_rewrite[$langdefault].'-'.stripslashes($imageType['name']).'.jpg';

 //old code
 //$newFile = _PS_PROD_IMG_DIR_.$image['id_product'].'-'.$image['id_image'].'-'.stripslashes($imageType['name']).'.jpg';
 if (!imageResize(_PS_PROD_IMG_DIR_.$image['id_product'].'-'.$image['id_image'].'.jpg', $newFile, intval($imageType['width']), intval($imageType['height'])))
 $errors = true;
 }

}

We add some code in AdminImages.php Prestashop Back Office. Following simple explanation to this new code.

$product = new Product($image['id_product']);

Getting the product object by create new instance of Product class by using id_product paramater.

$langdefault = Configuration::get('PS_LANG_DEFAULT');

We will using link_rewrite values for each product, we need default language because this variable is language dependent.

$newFile = _PS_PROD_IMG_DIR_.$image['id_product'].'-'.$image['id_image'].'-'.$product->link_rewrite[$langdefault].'-'.stripslashes($imageType['name']).'.jpg';

We have new snippet code to generate modified name for prestashop images. We hope this technique can boost our Prestashop SEO by inserting $product->link_rewrite[$langdefault] in prestashop images.

#2 Modify Link.php

In step #1, we have altered how images name are generated by Prestashop. The second problem is that prestashop themes system still use the old names to display their images. You will get website without product images for that.

Prestashop SEO Images Tips - Missing Images

So we have to modify how Prestashop themes system call our modified images name. File Link.php is located at ../prestashop/classes/Link.php Following our modified Link.php class.

public function getImageLink($name, $ids, $type = null)
 {
return ($this->allow == 1) ? (__PS_BASE_URI__.$ids.($type ? '-'.$type : '').'/'.$name.'.jpg') : (_THEME_PROD_DIR_.$ids.'-'.$name.($type ? '-'.$type : '').'.jpg');
 }

We have done this modification not more than an hour, please give any response or may be bug in this modification by commenting this post. Your support make this blog fresh. Thanks for reading.

We have try this SEO tips in Prestashop version 1.2.5, please give us any update from another version of Prestashop do you use.

Our results:

Prestashop SEO Images - HTML Source Code

Actually Prestashop already has image name url when friendly url is enabled. But there is a difference between default prestashop image url and our technique. I think Google prefer id_product-id_image-produk_name-image_type.jpg syntax better than id_product-id_image--image_type/produk_name.jpg because there are new slash in image name.
