PASSWORD - How can I modify the background image on password page
When your store is protected by a password, Trademark will allow you to display a beautiful, background image to collect emails.
You can easily change this picture in the theme editor. To do that, make sure that Trademark is your published theme. Then, click on this link. You will be redirected to the theme editor, right into the password page. On the left sidebar you will have access to a dedicated "Password" section. Click on it and you will be able to upload your own background image.
