Xee is useful as a more powerful replacement for Preview, or most any other image viewer available on Mac OS X. It is very fast, and uses less memory than most other image viewing tools. It also uses OpenGL to display and scroll images much more smoothly than other viewers. Its interface is highly streamlined and has easily configurable keyboard shortcuts.
