The text links are VERY IMPORTANT. I used link picture before because they looked nicer on the website, but it affected my website's ranking. At the recommendation of a friend, I've started working with CRT Business Solutions ( http://www.crtbs.com ) , an
SEO company from South of California, and they advised me to replace the pictures with text link and, eventually, add a picture behind the text or next to it thru CSS file, which I did. Even if the Page Ranking (
PR) of my website didn't change yet, I see every day that my pages are on a higher search results on Google, Yahoo and MSN. I am saying “my pages”, because every page is optimized for certain keywords. Besides changing the image links with text links, they optimized every page for search engine: unique title, url, meta descriptions for each one of them, content tagged with <h1><h2><h3> or <b>, etc. These are just few tricks they shared with me while they worked on my website. I'm sure there is more than that. Feel free to contact them. I really recommend their service.P.S.
