retrieving previously banned artwork

[bigredheadone]

I wish to retrieve  artwork I accidentally banned. This is the artwork received over the internet and not stored on my hard drive.
Is there a way to reverse previously banned artwork?

All of the banned pictures are listed in. 

/%AppData%/Banned Pictures.dat

Deleting the URL from there should do it.  I'd back it up first and do it with MB closed to be on the safe side.  Editing these dat files directly isn't exactly SOP.
