I searched on Wordpress’ plugin depot quite frequently for SEO goodies. Still I missed this plugin over formal searches but found it via google search accidentally.

The author homepage is no longer online and the WP page said it supported up to WP 2.5.1. Still I will give it a try on my 2.6.2 as it is really an effort saving feature for SEO. I shall report its usefulness in a week time if it works.

Here is what the plugin does for your SEO:

SEO Friendly Images is a Wordpress optimization plugin which automatically updates all images with proper ALT and TITLE attributes. 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 image 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.
