[F] "Google Images: Direct Links" filter update

[zoltan]

After about 2 1/2 years, the direct links filter is no longer working (tested in FF, Chrome, & IE). The 20 thumbnails with page navigation at the bottom are still loading, but the thumbnails only link to the full web page. I'm guessing that like last time, it's a URL match issue, but my experiments (adding "as_st=y" and such) have been unsuccessful.
