For some reason, this never occured to me that this was a thing... but I totally support this pairing! :3
...and then you google Elsa x Anna and it's almost all pics of them together in a non-romantic way...
I have the movie but haven't watched it...this is a really popular pairing...is there a reason for that? - Very nice pic!
Delusion. Romance/gay-starved fans. Etc.

There is a ton of content for this ship in terms of fanfics and art. Elsanna on tumblr, frozen + yuri on image boards, or the Frozen threads on /u/ are all good sources. You can also check out Yuri in Wonderland for some hard translated stuff.
But, OP, the creators /actually/ meant to have a little /gay/ in it. According to a friend I know who is a fan of Disney. I haven't really read which article they said it, but it was basically tl;dr, if the fans shipped Elsanna, they were successful with this movie. LOL
