The imgbed plugin removes the need for adding in markdown. You just paste the URL of the image and it adds the markdown on the fly using regexp.
Specify image size in markdown
@Spin0us Not out of the box, no.
By default the image will show full-size, or responsive to the topic width if it is larger. For most cases, that's preferable.
Recently (as of the last couple years, in any case), NodeBB will explicitly set the image size so content isn't shifted downwards as images are loaded, but there's still no functionality for a user to explicitly denote image size.
The reason why that is is simply that it is not part of the Markdown spec. It is possible to add, but it is not trivial, because you have to think about how you want to define that markdown code so it is readable to end-users too
Is there any plugins to add image size in markdown ?
Like in this topic
Is this supposed to still be a solution?
Found the latest version here but it's not working
