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/
Thanks for sharing this idea. Mockups can be inserted into a GitHub issue's description by inserting the image into the record's description in Aha! (see attachment). Any mockup inserted into the description will be displayed as an image in the GitHub issue. Mockups that are attached to an Aha! record will continue to be displayed as links.
