Add 1 default slider image

Hi!

First of all, thanks for this amazing theme, I’m using the free version of catch kathmandu.

Since I need to place in the homepage slider a list of picture but no link to post I replaced the default slider pictures with my personal pictures and it works fine! But I need to place more pictures, can you please indicate which is the code to add in order to have more default pictures in the default slider (and not only 3)?

Thank you for your help.
