Don't se it working jet…

Hi,

Thanks for your plugin, if it works i’ll be the happiest person on internet…
The site i like to use it on is this: https://www.oranje.twindaen.nl
I Installed the plugin, set the settings (although i don’t know if there richt), uploaded a picture checking the checkbox. But what now? Where can i find de pictures ID or shortcode? Can i place a shortcode like this in my visual composer?

Can you help me?!
