Is there a way to make an image inside a markup a lightbox so that it opens but also closes with the x at the top right

I tried creating a transparent image which overlays on tops of the markup and gave the transparent the same link, however, it does not close using the X so so i have to have it open in a new tab and hopefully people will know to close the tab but if there is a way to make a markdown do this or a work around, Im all for it.  Thanks
