All uploaded images show up as broken page icons

I’m not very fluent in code, or WP issues, so please forgive me. After upgrading to the newest version of WP, all images I upload from my media files now show up as what looks like a little icon of a broken page when I’m in my visual editor. My site is beautyjunkiesunite.com. Where do I go from here? I’m on a tight deadline and completely LOST! I cannot publish images in any new posts.

Thanks in advance!
