With Riva Slider, it is easy to link an image to a video. When editing an image, you can set the “Link Image Too” option to “Video”, and an option to insert the video’s URL will appear (along with some other settings).

Riva Slider will recognize links to both YouTube and Vimeovideos. Unlike other plugins, with the Riva Slider you can insert the link used to watch a video (directly from your browsers address bar) and the plugin will extract the video from that link automatically.
