SEO Friendly Images is a WordPress SEO plugin which automatically updates all images with proper ALT and TITLE attributes for SEO purposes. If your images do not have ALT and TITLE already set, SEO Friendly Images will add them according the options you set. Additionally this makes the post W3C/xHTML valid as well.
ALT attribute is important part of search engine optimization. It describes your images to search engine and when a user searches for a certain image this is a key determining factor for a match.
TITLE attribute play lesser role but is important for visitors as this text will automatically appear in the tooltip when mouse is over the image.
