Image Forensics : Error Level Analysis
If you’ve ever wondered just how much editing goes into a particular photograph, there’s now a super easy way to find out for yourself. Image Error Level Analyser is a simple web application that takes a URL to a JPEG photo and returns an image showing differing “error levels” in the image. Thus, you can now investigate any JPEG you find on the Internet to see roughly how much the photograph has been edited or manipulated. The app even gives you a permalink to the resulting image comparison.

I'm releasing the dataset for others to play with - see the bottom of this post for information.

If you haven't already set up goals in Analytics for viewing your pricing information, accessing the sign-up form, and signing up for an account -- go do it! It's vital information. However, Google Analytics' goals have to be attached to a specific URL. What if there is no URL for an important goal? For example, the New Account goal for Scout is just the account/show page -- there's no specific URL to represent a newly created account.
