That's what I thought, that it'd be like pasting in the coding for all those memes I've posted, but when I did that, all I got was the URL that's supposed to appear below the image, and no image.

The widget has a Flash component, but I'm pretty sure I have the latest version of Flash, and I can see the widget just fine on other people's pages. I just can't see it on mine. Maybe my LJ theme doesn't support Flash? Or something?
