Why aren't my homepage images clickable after adding rounded corners?

[pallavharia]

Hey Guys, 

I added rounded corners(border radius) to my images by editing the code. After doing this, the rounded corners only show when I adjust the image height to "adapt to image". Because of this, the images are not clickable. How can I fix this? www.tulum.coffee
