Comment 1 for bug 482060

Fixed so it wont error out on a guest comic.

class Bellen(BasicScraper):
    latestUrl = 'http://boxbrown.com/'
    imageUrl = 'http://boxbrown.com/?p=%s'
    imageSearch = compile(r'<img src="(http://boxbrown.com/comics/\S+.)"')
    prevSearch = compile(r'<a href="(.+?)"><span class="prev">')
    help = 'Index format: nnn'
