First of all, thank you for using our theme. Regarding the issue of the link, we can only suggest you to add it on the header menu or use second header layout and add link on the top left side. Other than this, we regret to inform you that there is no other solution. Also for Google translator and photo credit, we regret to inform that there is no other solution other than modifying the theme from itself from code level.
Since we do create and develop themes that is targeted for global users, the theme has predefined design and functionalities. Being such a case, it is impossible for the theme to have the functionalities that a particular user requires. We hope you understand it. But if you like, we can do the customization job for you. For that contact us on our mail.
