Keywords
In Smart Pix we use the term 'keyword' to refer to the descriptive words or phrases that you assign to an image. For example, you might add the keywords, 'German', 'blue', 'sports car' to a picture of a blue Porsche. In this way if you perform a search for German sports cars this file will be one of those returned.
While nouns or adjectives are most common, obviously there is no restriction to the descriptions that might be used, e.g.:
Porsche, Car, Red, Being Driven, 911
