I'm going to attempt to teach more people to fish ...

Tineye has a huge weakness in it that makes it useless for finding fake photos.  I'm not going to tell what it is on this board because I don't want to give away free advice to the fakers out there.  

You need to use google images to find these fake photos:

Step 1:
You somehow need to get a copy of the image on your computer because google images won't scrape the images off a page like tineye, but it will actually find matches for the fake photo.

Eros disables right click on the images so you can't right click and hit "Save Image As..."  Options around this are:

  a) temporarily disable javascript and then you can right click and save.  
  b) copy the file out of your browser's cache directory.
  c) use a screen capture and crop the image out

for Internet Explorer on Windows XP, your cache directory is in:

  C:\Documents and Settings\your-login-name\Local Settings\Temporary Internet Files

Step 2:
Go to: http://images.google.com/
 click on the little camera image
 click "upload an image"
 browse to the file you just saved in step 1
 google images then will give you images that it thinks match the image you uploaded

hope this helps.
