Embed Photo Plugin Found on ICanHasCheezburger.com

I’m trying to find the plugin used on ICanHazCheezburger.com. Under each of their photos, they include a small box that has the HTML code for the photo that users can copy and paste onto their blog or webpage. What plugin is this? Is there others out there that will do the same thing? Do you have to produce the plugin yourself?

Any help would be greatly appreciated, thank you so much!
