iSmartPhoto is a fast image browser and powerful image organizer. Unlike iPhoto, iSmartPhoto doesn't require you to manually import photos -- it automatically pulls your photos from any folder or drive. By just double clicking a single image in Finder or dragging a folder, iSmartPhoto automatically displays every image from the selected folder and its subfolders.
iSmartPhoto can automatically group your photos by modified date, image format, image size, file size, GPS location, rating, flag, tags, and EXIF information such as camera model, lens model, F number, exposure time, ISO, focal length, and IPTC information. iSmartPhoto natively supports all popular image formats like JPEG, TIFF, JPEG 2000, BMP, PNG, TAG, RAW, and any other image format supported by OS X.
