In Ghost, the markdown for image is
![alt](src)
Is there a hidden format for adding a class in the img tag? Or is this feature not in G
img
this is perhaps too obvious but you can put it in any element you wish i.e.
![](...)
and then use css inheritance
.myDiv img { width: 50px; }
since markup in ghost supports html (probably most do) you can also do regular tags as well
