Compare Images
You can use the Compare Directories tool to compare images. If you double-click a line that contains two different images, the Compare images window is displayed. This dialog box presents the images in the left and right sides, scaled to fit the available view area. You can use the contextual menu actions to scale the images to their original size or scale them down to fit in the view area.
The supported image types are: GIF, JPG, JPEG, PNG, and BMP.
