Make featured image clickable on front page?

Hi WP-members!

I hope for your help. I’ve been all over the web looking for a solution but have not found one. I’m using a static page as front page which shows my main posts as small thumbnails. My theme (Custom Community) adds a grey box with the excerpt half way on top of the image, which shows when hovered. The problem is, the featured image itself is not clickable, only the title in the grey box. This is not optimal seen in a user experience.

Is there any way to come around this problem and make the whole image clickable? Any help would be much appreciated. My knowledge in php is quite limited, but I’m pretty skilled in copy paste ??

Thanks so much in advance.
