Pictures Inspector play online

This app is a pictures comparator with a useful feature that is described by the followed use case:
You want to compare two pictures with the same object to find the difference. But they were made with the smartphone camera, so they differ in offset, scaling, rotation and screw. This app can help you. You only need to load/take the pictures and define the calibration points. Now the misrepresentation does not matter anymore.
