The Alt attribute is a way for HTML documents to specify text as an alternative for Graphics. The use of Alt attributes (also called Alt tags ) is mandatory according to W3 standards, although many web developers forget them.

Alternative text is especially useful in the following situations:

*People with low bandwidth Internet connections, who may opt not to load graphics. *People using Smart phones with browsers, such as the Blackberry *People with disabilities who use assistive software or screen readers *Search engine optimization. Search engines can only interpret the meaning of graphics by analysing the Alt attribute.
