You simply navigate the directory structure as desired and any image files found in a directory are displayed in miniature (Thumbnails).
The Image viewer (Browser) is similar to Windows Explorer. XnView can also display video formats, many digital camera formats and more exotic formats such as Amiga IFF and Calamus. XnView is able to read more than 500 different formats and then convert them to other formats such as GIF, BMP, JPG, PNG, multi page TIFF. With XnView you can quickly and easily view, process, organize and convert image files. There is also an automatic panorama stitching tool. All edits are saved automatically, but can be reverted at a later time. Clicking the “Fix” button gives you easy-to-use tools for adjusting exposure, color, detail (sharpness), and for cropping and removing red eye. You can browse the pictures on your computer by folder or by date, and you can add keyword tags, ratings and captions for even more organization. Windows Live Photo Gallery helps you import your photos and videos from digital cameras, camcorders, CDs, DVDs, and Windows Live Spaces. I especially like the Picasa Web Albums integration which gives you 1024 MB of free space to post your photos online. Picasa is excellent for beginners and casual digital shooters who want to find all their pictures, sort them into albums, do quick edits, and share with friends and family. Picasa is a flashy and functional digital photo organizer and editor which has improved considerably since its first release. It supports all major graphic formats (BMP, JPEG, JPEG 2000, animated GIF, PNG, PCX, TIFF, WMF, ICO and TGA) and popular digital camera RAW formats (CRW, CR2, NEF, PEF, RAF, MRW, ORF, SRF and DNG). Other features include a high quality magnifier and a musical slideshow with 150+ transitional effects, as well as lossless JPEG transitions, drop shadow effects, image annotation, scanner support, histogram and much more. Its innovative but intuitive full-screen mode provides quick access to EXIF information, thumbnail browser and major functionalities via hidden toolbars that pop up when your mouse touches the four edges of the screen. It has a nice array of features that include image viewing, management, comparison, red-eye removal, emailing, resizing, cropping and color adjustments. FastStone Image Viewer is a fast, stable, user-friendly image browser, converter and editor.
