Mockups are being sent to github as links, opening the image externally, instead of showing them directly in the issue. Prepending the link with an exclamation mark would show the mockup inside the github issue, a much useful approach.
Current mockup link in github : [name](link)
Expected mockup link in github: ![name](link)
Reference, stating that image links should be prepended with an exclamation mark: https://guides.github.com/features/mastering-markdown/
