With imageDiff you can:

* Compare two images and see exactly what has changed, down to the pixel.
* Compare images in different formats with each other, including JPG, GIF, BMP, TIF, PNG and more.
* Compare images of different sizes, imageDiff will scale and compare them automatically.
* Choose between four different visualization filters to highlight differences the way you want.
* Overlay the original image to see exactly where changes have occurred.
* Report the percent of pixel and color change, a great way to see the effects of image compression.
* Adjust the comparison tolerance to ignore, or allow for, compression noise and artifacts.
* Switch between larger thumbnail views of the images to evaluate changes for yourself.
* Save the comparison image for reference or to be able to show others the image changes.
* Use the full-featured command line to run imageDiff from a script or plug it into other programs.
* Configure imageDiff as your default comparison program and set up a passthrough program so that non-image files are passed to a traditional text differ. [From IonForge]
