If you are an avid photographer, then your PC must be used to store lots of images. Its often becomes difficult to search for an image from the large pile of images (Even with very less number of images, I find it difficult to search one).
You can easily organize your photos using tags. To add a tag to a photo, right click on the photo, Properties->Summary. Here you can add the tags in the keywords field. Make sure to separate the tags using semi colon. You can also tag multiple photos using the same procedure.
Once you have tagged the photos, its easy to search for them. Click search on the Start menu or press F3. Select Pictures and photos and click on Advanced search. Enter the tags in the textbox- “A Word or a Phrase in the File” column.
You will be able to easily search for the photos with the particular tag.
