Picture not showing up.

Total new guy. I’m making a portfolio site, and on the About page I am trying to include a picture, (small .jpg) that the text will wrap around. The space shows up, but it’s blank. The image is in the library, and I browse to find it, then it shows up in the Visual editor just fine. Not on the page after I save changes. Cleared the browser cache, nope. Any ideas? I’m sure it’s something really simple.
Thanks very much in advance.
