Linking of images in Featured Slider

Hello guys, First of all, thank you very much for the theme, it is incredibly good looking and perfect for my planned site. Now I have a question related to the featured slider. I have my own images there, as I set successfully a featured image on each page. However, I would like to have the possibility that when the visitor clicks on the image or on the text "Flight", he is directed to a page with all posts marked as "Flights". I managed to do that if you click on "flights" in the header menu, but I am not able to do it if you click on the image. Any chance to do it? Another smaller thing is that between the 4 featured images from the features slider and the posts in the featured grid content, somehow a small gap appeared. Is there a way to remove it or is it related to the size of the used images? My website is www.trip2day.com and many many thanks for your help and support! :) Regards, Fabio
