Maybe. Google+ interaction is heavily skewed in favor of picture posts and other things that people can admire at a glance and click +1 on. There’s a good opportunity to reuse content that you post to Instagram here. You can also host all of your pictures in Picasa (the picture app built into Google+) and pin them or link out to them elsewhere (as opposed to hosting them on Flickr or Facebook).
Maybe pictures of puppies aren’t such a bad idea. Borrow someone’s puppy and pose it with your product. Make LOLcat memes about your brand.
Or you could have your girlfriend run your Google+ campaign for you. Clearly she has some natural talent!
