Changed cover pic for Written Script's Bad Day

Okay, so after Snogwritts did his reading of the fic, I realized the picture he found of Script was so much better, and so I decided to use it, with a bit of downsizing so Script is the only pony in the pic. (And credit to Snogwritts for the pic idea.)

Here's a link to the full pic if you're interested.
