Was to late to edit my own message, sorry for that. It was not only the spacers you used but the entire markup was bit off a mess. A lot of unnecessary content. I made a quick makeover. I hope this helps you somehow:

<h1>About the Author</h1>
<img src="images/About_photo1.jpg" alt="Photo of author Walter Kornichuk" />
<p>
In 2000, Walter Kornichuk was diagnosed with a brain tumor and given a 40 percent chance to survive five years. He survived six hours of awake motor mapping brain surgery and radiation and chemotherapy treatments by applying a "never give up" attitude to endure his brain tumor. He is happy to celebrate his tenth year of cancer-free living. He has been a volunteer for the National Brain Tumor Society-Patient and Caregiver Support Network since 2006. He has been a Lead Transportation Security Officer for a private security company at San Francisco International Airport since 2003. He is a first-time creative non-fiction writer and has self-published Cancer on my Mind, which includes a talking brain tumor, to bring a humorous and unrelenting tone to patients diagnosed with a brain tumor, a dark and otherwise not easily discussed subject. Walter hopes that cancer patients, brain surgeons, doctors, nurses, medical students, caregivers, all readers, and those facing any life-threatening dilemma, will feel encouraged after reading Cancer on my Mind, to fight constantly to obtain short and long victories.
