Which problem?

When I try to load images by an url the app freeze

You can use Collin trees extension to load image from url asynchronously.

and how can i put this images into the card view after i loaded it with colin ?

First you have to store image url on a global list and use the element index option of Colin to fetch the image url from global list variable and display wherever you want.
