While the low cost of digital photography means that we take more shots than ever before, this financial benefit has a different cost.

Only by using very long names could you expect to include all the words you might want to search for. Using a sensible arrangement of named folders and sub-folders is also a good ideas but it too has its drawbacks. A photo can only be in one folder but it could represent several themes that you might want to search for.

Windows’ tagging feature solves this problem by allowing you to assign any number of tags to each photo. Here's how to tag your photo library in Windows 7. If you have Windows 8, and you can't see the details pane when you select a photo, press Alt-Shift-P, or click on the View tab, then Details pane.
