How to resize images in Ghost
The current version of Ghost does not support image resizing, so the workaround for now is to use HTML tags with some CSS crammed in:
<img alt="Image Description" src="/content/images/my-image.png" style="width: 300px; height:300px">
Not a best practice, but since it is only height and width there shouldn’t be any major problems as a result.
Solution originally from this post. Thanks to wdiaz.
And for including the above code inline, the backtick (`) is used, per the Ghost Markdown guide.
