Problem with the thumbnails

-- HikaShop version -- : 2.2.1
-- Joomla version -- : 2.5.14
-- PHP version -- : 5.2.17

Hello, do not know what happened to the product thumbnails on the frontend, are distorted! I attached a picture. What could have happened? Thank you.

Hi, I have the template made ​​with Artisteer. Previously had established a page width of 1400 pixels. This afternoon I have changed so that the width is 90% of the available resolution. It's the only change I made to the template. In several resolutions, the thumbnail images are stretched and distorted. The CSS file to which you refer, is that of my template, or one that is within HikaShop? Thank you.

Hi, I solved it by editing the frontend css file in HikaShop > Configuration > Display > Public Site CSS File > Custom.

I find the next code:

img.hikashop_child_image{

  margin : 2px;

  height:25px;

}

img.hikashop_child_image{

  margin : 2px;

  width:100px;

  height:100px;

}
