You can add galleries to your gallery directory in two different ways.
When creating a new gallery: jump to section
By going to the Gallery Directory Tab: jump to section
Method One: When Creating a New Gallery
When you create a new gallery, the Create New Gallery box will pop up. Type in a gallery name and fill out any other details.
Go to the Gallery Directory section and select the Display in Gallery Directory checkbox to add your new gallery to your directory.
After selecting the checkbox, click the Next: Choose a Cover Layout button.
Note: You will also need to publish your gallery for it to be viewable in your gallery directory.
Method Two: Add An Existing Gallery To Your Directory
To add an existing gallery to your directory, go to the Galleries page. Click on the Directory tab in the top vertical menu.
If you scroll down the page, you will see two columns.
On the right, the Non-Directory Galleries column lists the galleries that are not currently in your Gallery Directory. All galleries will be in this list by default.
On the left, the Directory Galleries column lists the galleries currently in your Gallery Directory.
To add a gallery from the Non-Directory Galleries column, click on the Add button.
To remove a gallery from the Directory Galleries column, click on the Remove button.
Note: You can also easily publish or unpublish your galleries here by clicking on the blue Published text or red Unpublished text.
