Courtesy of Pottermore, here are some gifs about the Harry Potter (book series). Be sure to pay extra special attention to the last one (Deathly Hallows), as it is exclusivley for the Harry Potter Wiki and important in understanding the new book.
Also check out this video of all the Gifs!
Don't forget to head over to the Pottermore shop! You might find something magical that you can't live without!
