Rollover effect in pestashop 1.6.0.14

[Lulu79]

Hi to all! ​what to do to have a rollover effect of the images featured in home and product list?

 

I tried to change product-list:

 

 

<div class="product-image-container">

<a class="product_img_link" href="{$product.link|escape:'html':'UTF-8'}" title="{$product.name|escape:'html':'UTF-8'}" itemprop="url">

<img class="replace-2x img-responsive" src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home_default')|escape:'html':'UTF-8'}" alt="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" title="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} itemprop="image" />

                            {if !empty($new_idimg)}

                                <img class="replace-2x img-responsive second-img" src="{$link->getImageLink($product.link_rewrite, $new_idimg, 'home_default')|escape:'html':'UTF-8'}" alt="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" title="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} itemprop="image" />

                            {else}

                                <img class="replace-2x img-responsive second-img" src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home_default')|escape:'html':'UTF-8'}" alt="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" title="{if !empty($product.legend)}{$product.legend|escape:'html':'UTF-8'}{else}{$product.name|escape:'html':'UTF-8'}{/if}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} itemprop="image" />

                            {/if}

</a>

 

and I modified the css, the rollover effect works but the two images are the same ..

 

Thanks in advance.
