Only images from github are displaying

[PenaflorPhi]

I'm trying to display an image in the preview but I'm not sure if I'm doing something wrong. If I upload the image to github it displays correctly. What I'm doing on my file is

![1](https://imgur.com/Image.png)
![2](/home/user/path/to/file/Image.png)
![3](./path/to/file/Image.png)
![4](https://camo.githubusercontent.com/verylongstringofnumbers) 

1 - 3 don't work, the browser (Firefox, Firefox-Nightly and Chromium) either display nothing (not even the string of text) or they display an empty rectangle. The fourth one works but it's the link that GitHub gives after putting the first one in the readme, is there way I can display images without putting them in GitHub?

It should work and display local image or any other online image. make sure your path is correct，please check the browser network if it does not work.

Markdown code.

# hello

And I got this error. How to fix that

[iamcco]

The image (https://i.imgur.com/W7jfX9h.png) you insert in the markdown file is forbidden to display by imgur

Change 127.0.0.1 to localhost to see if it can display. I don't know if it's because imgur block IP website

Yes, change to localhost would work
