After randomize the appearance of featured products on homepage, the product images doesn't show

[BAlexandru]

Hello,

 

I'm using this module for featured category products on homepage: https://mypresta.eu/modules/front-office-features/featured-products.html  but i have a little problem. I wanted to randomize the products that appear on homepage and now the images aren't showing anymore.

 

And here is the modified code:
