After I set up webpage (www.billingsbygeorge.yolasite.com) I was not satisfied with my choice of a picture of a woman in a standing karate pose on my "Services" page. I attempted to edit the page by inserting a new (HTML) picture of a woman in an action (kicking) pose. After editing, I saved the change and logged out. When I pulled up the website, the old picture was still on the "Service" page of my website instead of the new "Kicking Karate Girl." I rebootted my computer and re-edited the page, again inserting the new picture. Synptoms prevail...old picture. How can I edit the page?
