Good lord! Google doesn't care for pictures. Google looks at your text. Google is not a person that sits behind a monitor and actually "looks" at website and determines which is the prettiest!

Google is a robot that goes around looking at your code and sniffs out headings (stuff between <h1>, <h2>, <h3, etc... tags). Stuff in bold also.

Don't put all you text in bold or on heading ... it's smart enough to look for that.
