Remove images from the repository

[BeayemX]

You don't have to have the image files inside the repository.

Steps to link images:

1. Copy an image to the clipboard
2. Create a new issue (you don't have to submit the issue later on)
3. Paste the image to the text area
4. "Uploading" should be displayed
5. A link is created that should look something like this:
   ![image](https://user-images.githubusercontent.com/3453076/35476422-c8b16542-03af-11e8-99f3-ebc77e15c60f.png)
6. Use this link in your ReadMe file
7. Discard the issue (the link to the image will still work)
