Images not working on Express webpage

I’m trying to use images on my webpage. They are able to be uploaded just fine and the link works for me, but whenever I try to use the image in the page it doesn’t load and just shows the alt text. When I use the same image on a different site it works fine. How do I fix this so the images will load? It’s not an issue of the URLs being changed somehow, it’s just not loading.

Update: It’s an issue with a package I use called helmet, which I use to require https. I’ll switch it out now. The bottom line: DON’T USE HELMET IF YOU PLAN TO USE IMAGES.
