popup for displaying my YouTube video when someone clicks on image

Greeting All,

I was trying to put a kind of media gallery in some client’s project.
The thing I need is to connect YouTube video to image, and if someone clicks on that image, I need a popup that plays YouTube video.

I don’t want the user to go to youtube.com or redirect there, I just simply want them to stay on the same site and video popup to play there on same site.

Hope i have described my problem clearly, need suggestions $ help from your side.

Thankyou
