Ah. So, in your image library you need to copy the URL of the image. It will be something like: `<a href="https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461`" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461`</a> Once you've copied the image URL, you can paste it into a regular Markdown image link: `[Some Text](<a href="https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461)`" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461)`</a> However, because the URL doesn't end in .jpg, .png, .gif, it will show up as a link. To hint the chat system that it actually is an image, you add an HTML fragment to the end ( #<something> ) which has one of the above extensions: `[Some Text](<a href="https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/16204335/MGS1pylFSsnd5Xb9jAzMqg/med.png?1455260461</a> #.jpg )`
