This fast, free browser is easy to use, highly customizable, and supports a staggering 400 file formats. There's no reason not to have it for those rare and unusual file types, plus all the useful functions it provides such as quick edits and batch processing. Despite being a user for many years, I'm always finding more and more that it can do. It's available for several operating systems--even portable devices. Unfortunately, the developer has temporarily stopped distributing the Mac version in order to start from scratch on a new multi-platform version.

XnView - Free Picture Viewer, Thumbnail Browser and Image Converter
XnView is a fast and free image viewer and converter with support for a staggering number of file formats, operating systems, and languages. XnView can import over 400 graphics formats, and writes about 50. It's highly customizable and doesn't do annoying things like take over all your file associations without asking or leave files in all your folders. XnView gives you the option to create a thumbnail cache or not, but even without caching it is still very fast.
XnView provides a number of very useful functions such as batch renaming or resizing, cropping, generating file lists, removing red eye, creating contact sheets, and a whole lot more. It even offers photo organization tools such as keywords and categories, ratings, captions, and metadata support (EXIF, IPTC, XMP).
In the past I felt like some features were a little weak and the help file was poorly written, but so much has been greatly improved in recent versions. Some users might not understand all the options; although the help file is much better now than it used to be. However, there are still some areas where it doesn't match up with the current version.
For basic image viewing, sorting, browsing and converting, you can't go wrong with XnView. It's certainly worth keeping on hand for those odd file types we all come across from time to time. Some might even find it powerful enough to use for everyday digital photo management. If you ever used ACDSee back in the day when it was still a simple image viewer, XnView will seem very familiar to you.
Windows users may also want to install the XnView Shell Extension, which provides an image preview and conversion options from the right click menu in Windows Explorer.
