A:
No, the JPEG file format has no inherent support for animation.
The image you linked is actually an animated GIF disguised with a jpg file extension. (The browser apparently ignores even the MIME type and looks at the file header bytes in such cases.)

It is a GIF image... the extension has been changed by hand. Browser engine is smart enough to determine image format regardless of file extension.

If you view the image in firefox, you can right-click on it and select properties:
You'll see Type: GIF image (animated, 54 frames)
Thus, it is a gif-image that has been renamed to .jpg.

1 more reason I love Firefox for web development. You don't even need to view the properties, its right there (with the dimensions) in the title bar!
