Latest post + popular destinations

1. I try to do some “latest posts” with image at my homepage but when I use “widget latest post” the image is so small. I want a easy way for my visitors to see latest posts with images soo they can click and read more. How?

2. Also I tried to use “popular destinations” but I want to choose 3 destinations from the category but can only choose 1? Is it only possible to have 1 popular destination?
Also why arent all my categories in the category list in popular destination? Only some of them are and can be choosen
