I've had a few people come to me with problems logging in to a gallery so I just wanted to put this guide up to try to help anyone having this issue.

There are 2 ways to log in and I will explain both.

You will need to put in your email address, click next and then use the gallery password.
If it does not ask for your email address, please click on the Back button to go back to the email entry page.

The gallery password screen looks like this.

If you have logged in previously and have added any photos to your favourites, it will ask you to create an account.
This is so it can link those favourites to you and when you log back in, it will have them saved.

The account login screen looks like this.

If you have forgotten the password to your account (from adding favourites previously), on the home screen, you can click on the little profile head to fix it.

The little profile head is shown below.
