Change image size on Instantsearch page

Hi,
I only testing Algolia search and i try to change image size on Instantsearch page as you suggest: https://discourse.algolia.com/t/image-size-on-instantsearch-page/1593.
Now I see in index two image links:
1. to thumbnail 150×150
2. to full (to which I want to change)
But on Instantsearch page i see thumbnail 150×150 still.
Could you help me to fix it?

Thanks, Dmitry
