Insert Media – problem

Hello! My congratulations for the plugin, it is wonderful.

I have a problem, I can not use the button add media to insert pictures (some of my posts have 30 pictures).

So I write everything in html and then have to convert into a site that makes html2markdown.

Is it possible to add line average insert html code for images?

the option “convert html to markdown” never worked for me, everything is white.
