I am trying to add a custom logo and I put it in this directory: http://www.website.com/wp-content/themes/flexibility2/images/logo.png

I have tried both a .png and a .jpg file. The size is 440 by 110 pixles. When ever I goto my site, the header is blank, it does not contain the logo at all, and it doesn't even have the Blog title and tagline, yet you can still click in that area to goto the Home page.
