Plugin for image alt attribute?

I don't know any html. Is there a plugin that allows me to add the alt tag to images easily?

 

just find the '<img src="..." />' tag in the html (open the file in a text editor and do a search for img if you can't see it...) and add 'alt="your alt tag"'......

 

Well you dont need any plugin
But its a simple thing :
