Simple HTML thing wanna get clear.!

[Face]

Hello Friends,I wanna get something clear about HTML work.

First see this code

<div ><a href="http://www.ooooo.com"><img src="http://oooooooo.jeg" alt="my page" width="100" height="33"/></a></div>

alt means what ?& why we should use this?

I use some related thing in that alt="oooo"

Is it a use less thing or what is the advantage we get with that,?>
