IMO, Downloading Images off the Gnutella Network is like playing Russian Roulette. Eventually you're going run out of Luck. Sooner than Later.
The available Images for download are Loaded with KP, Viruses, Worms, Trojans, and Corrupt or Fake Files.
There are Many other sources out there for Images that won't compromise your Security and Computer.
Try Google.
You will also want to Stay Away from Game, and Program Files, for the Above Mentioned Reasons.
This is just my Opinion.
