[Prestashop] First product image as cover

If you want to mark first image of product as cover you need to do:

  1.  Open your database (for example by phpMyAdmin)
  2. I suggest you create backup of your database for safety (export data and structure)
  3.  Open SQL tab and perform queries from this file (change ‘ps_’ to your prefix):
  4.  Done! 🙂
