FastStone Image Viewer

FastStone Image Viewer is a fast, tiny image browser, converter and editor that supports all major graphic formats like BMP, JPEG, GIF, PNG and ICO. It has a nice array of features such as image viewing, management, comparison, red-eye removal, watermarks, resizing, cropping, color adjustments, musical slideshow and more.

Some nice features

  • It's simple, it takes very little system resources.         
  • Draw texts, lines, highlights, rectangles, ovals and annotations on images
  • Slideshow creation with 150+ transitional effects and music support
  • Image EXIF metadata support plus comment editing for JPEG
  • Batch convert and rename support.
  • Image special effects: watermark, annotation, drop shadow, framing, bump map, lens, morph, waves                          
  • Multi-language support
If you want to find a lightweight and full-featured image viewer, FastStone Image Viewer is definitely a good choice.  I think the only weak point is its interface looks a bit confusing and not very attractive, but you will find out that the default design is useful soon.
