Integrating Design Center with external website

Hi! I'm currently trying to figure out how to integrate the design center into an external website using a customer's design center. Under HP Application Center I have a customer who wishes to integrate onto their website a means of linking to their design center without having to login so that their clients can access and use the design center without a password. Currently, they are using the external link provided under their customer page on the HP Application Center however this leads their clients onto their login page and not directly to their design center. Is it possible for them to place a hyperlink on their website that allows their clients to access the customer's design center and not our design center? Editing the website with WordPress and only need access to banners, roll-ups and posters in the Design Center.
