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 box that prompts you to add your gallery name, date info, and description also has a Gallery Directory section.
Check the Display in Gallery Directory checkbox to add your new gallery to your directory.
After checking the box, 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 menu, and click on the Directory tab. 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 in your Gallery Directory. All galleries will be in this list by default.
On the left, the Directory Galleries column lists the galleries you currently have 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Note: You can also easily publish or unpublish your galleries here by clicking on Published text in blue or Unpublished text in red.
