This is a great tutorial from +RC Concepcion on how to set up Lightroom to make it easy to make your Google+ cover photo into a collage.
And also check the link for the first video where he showed how to do it with Photoshop and Bridge.
Awesome tips that are useful for other things besides just your cover photo.

Make a New Google+ Cover Page w Lightroom
Yesterday I made a video after +Sara McKinley post on the changes to the cover image: (link: http://bit.ly/WUbLtN ). The video showed how to make a cover photo collage in #photoshop . +Stephen Dickson asked if there was a way to do this in #Lightroom – so I made a 90 sec video on that. If you find it helpful, share it out.
