Can't instantiate UI Image prefab

Hey, I have this annoying problem that’s driving me nuts and I cant find any solution to it. I want to Instantiate an UI Image prefab via script. I have a public Image variable that I set in inspector, and when I try to Instantiate this I get “The object you want to instantiate is null”. It’s funny, because I can instantiate an UI Button prefab the same way I want to instantiate the image.

line 70 is working perfectly, while line 71 is throwing that error.
Any help will be appreciated, thanks

If someone else is having this problem for some reason, I worked around it by making the UI Image from scratch; by making an GameObject and adding different components to it via script.
