Link for an external site

Hello, i am using the creative theme to make my portifolio (https://themes.gohugo.io/theme/creative/)
But i need more options to show my projects on each one’s page.
For example, i cant use more than one image on the yaml content file.
Is there a way i can made the portifolio section images to open a new windows to an external site?
Or even open an external site on the project panel .

Thanks in advance.
