How to display image on WordPress homepage

I’m trying to display an image through my home page in WordPress, through my text editor on the page, but nothing displays. It works on other pages, just not on the home page. When I press publish, it says updated but when I check the source code nothing shows up for the image. If I publish it through css it works to get it displayed
,but can’t select the image in the way I could if I enclosed it in a div class. If I display it through a homepage text widget, it publishes twice, in different sizes-once in the body and once in the footer.

Image html

And html controlling homepage.

Css

parallax-window controls the home page I think.
