Post format "Image" – I need active link

Hi,

I want by clicking on the image of the post, to open my the post, not the image itself.
My post format “Image”.
I saw that in other formats posts by clicking on the image opens the post, not the picture.
I want the same thing happens as with this format post format “Image”.
What should I do?
Which php file should be changed and how?
The theme that I use is Pinboard.

Thanks for your time.
