It is truly amazing what can be accomplished with some editing tools these days, tools such as Adobe’s Photoshop. Using such a software solution to brush up photos, or create mind boggling effects is cool; what is not cool is using Photoshop to edit a picture and then go tell the world that it is for real. Luckily enough, with Error Level Analyser you can now put these images to the test – think of this piece of software as an imaging polygraph test of sorts.

This 20KB software program developed by Noah can be used to measure error levels in JPEG images. The algorithm used here is somewhat similar to the one presented by computer forensics specialist, Dr. Neal Krawetz. There are five simple tasks that you can accomplish with Error Level Analyser:

1. Load the image you wish to analyze.
2. Save – this is self explanatory.
3. The “Work” button, once you click it, will start the analysis program which will produce a heat map.
4. The “Trackbar” will point out the differences between compression levels.
5. The “Text Box” can be used to modify the scaling factor.

“If, after loading an image, you move the track bar, the difference for a particular compression level will be shown. Each tick is five levels, going from 0 on the left to 100 on the right. By default, the differences will be exaggerated by a factor of 10 to highlight differences. If you wish to use a color scaling factor other than 10 simply type it into the text box on the toolbar. And if you believe that, you'll believe anything,” says the official tinnyappz presentation.
