Chasing down those fake pictures
Everyone may know this, but for those who don't and wonder if all those pretty girls are posting their own pics, here's how you tell. Go to Gxxgle search engine and click on images. Then:
Right-click an image on the web and copy the image's URL. (using the drop down menu)
Return to the search box and paste in the URL (Ctrl+V or Command+V).
Tip: Try dragging an image into the search box from your desktop or the web.
Multiple hits will tell you the image has been stolen and does not belong to the poster.
Tineye also works, but not as well. There are other ways, but this one works easily.
