ImageFinder will help you to find and remove identical and similar images from your machine.
ImageFinder has two modes; find identical pictures and find similar images. The first mode, the duplicate picture remover searches for completely identical image files. In the second mode, the app's similar image finder searches for images which are different but are the same images. For example, it may be two images from the same image but of varying size or dimensions or various shades of color, etc.
ImageFinder allows all duplicate images to be previewed as thumbnails and can be sorted by size, name, creation/modification date, or by dimensions.
