"Side by Side" group made to collect those kinds of photos that are contain of two photos or more than two photos in one picture.
It calls "Diptych"

Everyone can join the group, but it doesn't mean all of your works will be accepted here.

When you Contribute your photo to gallery, that will take time to accept by admins. Those kinds of photos are acceptable that are right for group focus, it means that they must be at least contains of two photos in one picture.
(Note: If you submit any photo that is just a single photo, that wont be accepted.)

If you want to suggest favorites, they must be at least two photos in one picture. (just like what told above)

[Important: After that you suggested favorites, and accepted by admins of the group, you have to post a comment on that photo that you have suggested, and let them know where you have Featured his/her photo]
{Example comment: Featured as Favorites in [link] }

"Diptych" album is about those pictures that have couple of complete photos beside each other, but "Multi Exposure" album is about those pictures that have couple of photos that are placed above each other and have some fade look. (to understand better, you can take a look at both albums and see the difference between photos in each album)
