Digital images

Advantages:

• Google is the largest and most popular image search 
• Image searching is quick and easy
• Offers simple and advanced search
• Allows sorting options eg black & white, faces, image type 

Disadvantages:

• Google Image Search uses text (your search terms) to search for images.
• Google searches for the search terms in: the filename of the image or the link text pointing to the image or text adjacent to the image. 
• Google makes a guess that the words are related to the image.  
• There is no standard meta-data accompanying images.
• Google technology isn’t yet to the point where it can tell what’s in an image by looking at it directly.
• The images identified by Google may be protected by copyright.
•  Google cannot grant you any rights to use images for any purpose other than viewing them on the web.
•  Accordingly, if you would like to use any images found through Google, you must contact the site owner to obtain the requisite permissions.
• There are other images, held within databases, that Google is unable to index.  Some of these are likely to be better than those found via Google.

•  Google cannot make adequate assessments of the aesthetic quality of images they index or an image's suitability for your particular purpose.
