Images from Imgur not showing up in posts?

Update: I just switched from Imgur to catbox.moe and it works now lmao! Apparently Imgur is just the worst haha

I’m trying to add images to my blog from my Imgur, but they aren’t showing up…

They do show up in the live editing thing, where you can just insert an image by pasting a link. But once I save the post and view it, they’re either gone completely or a blue square with a question mark. When I go back to edit, they’re still there.

I’ve triple checked the urls, and made sure they include the file type, too! Also, one of the blog posts was working before, and doesn’t now.

 could this be a spacehey issue? Is it Imgur’s fault? Am I just doomed to forever be bad at coding? Help!
