Circular user portrait in left side rail not showing up

[jeromecovington]

Should my user image be showing up in the left rail of the homepage and posts (as does the Gandalf image in your sample screenshots)? It may be that this is an issue with how I have my blog configured, but I have a user image associated with my Ghost account, and it shows up in my blog admin, so I figured it would show up automatically in the left rail on my blog when using the Solar theme, as well.

Great theme, by the way, it will come in very handy when demonstrating code samples within Ghost blog posts!
