Did you know that now your google plus profile has a big banner behind your profile pic? They called it a "cover photo" pretty much like Facebook timeline cover with different layout and setting. It has a bigger profile photo with longer horizontal background banner. If you are concerned with your personal branding, creating a good impression for your Google+ visitor is vital.
I've played around with coverphotoeditor.com and it does a nice job - upload a couple of photographs, one of your background, and one of (probably) you, then you can save, then upload. Of course, you could just go and do the whole thing by hand, but this way you can fiddle around a little bit. Seems to work well. Very simple and quick. You can take a look at my G+ profile page if you like - I won't inflict it on you directly!
