Help with JSON-LD Request

Hello-would it be possible to find examples of both a video AND and image marked up with the JSON-LD?I am new to this markup stuff but am excited after finding the Google Markup helper...I am marking up all the pages I can of my websites but the Google Tool so far is limited to certain types that do not include Images or Videos ( I have an Image Gallery on one site and a video gallery on another)Seeing an example markup of both would make it possible for me to wite the JSON-LD for my videos and images...Thank you Thank you!
