Lena Levin shares instructions on how to create photo albums of your art on Google + :
If you add photos not from the main Google+ page, but from the “Photos” tab, you can do either of two things:
1. Add one or several photos from your computer and create a new album out of them; after you have done that, Google+ automatically offers you to share (at which point you can add some text to make a post to accompany the photos). If there are three photos or less, the post will include a “panel” with all of them; if there are more, it will show a panel with the first three.
2. Essentially the same thing happens if you add your photos to one of your already existing albums: Google+ offers you to share, and, by default, it will include in the post only newly added photos: if there are three or less, they will be all visible together, in a panel.
The latter option works better if you have “thematic” albums — in this way, if someone clicks on a photo to view a larger version, they might also browse the whole album (note: if you click “Photos” from my profile, you will see that I have lots of such albums). It works as a “gentle nudge” to the followers to browse more of your work. 🙂 Quite often, this really happens — I see that someone goes through the older images and adds “+1″s or comments.
And it also offers those willing to share your work to their followers an option to share a whole album, rather than a single post or a single image.
I cannot give you links, because I am figuring this all myself, more or less (especially because they rather frequently change how it all works… :).
