If you see an image posted somewhere on the Internet or have one sent to you by email that you suspect has been " photoshopped", i.e. digitally altered, are there any methods that will assist you in making that determination? There are indeed methods and tools to assist you. If the image is a jpeg image, you can upload the image or submit the URL for its location on the web to the Image Error Level Analyzer. Additional information on how to detect "shopped" images can be found at Body By Victoria and Photoshopping and Digital Forensics.
