If you've run across the phrases, "publish your gallery to add a client”, or “publish your gallery to add it to your Gallery Directory", that means the gallery is not viewable.
Step 1: Go To Your Gallery
Go to the gallery you want to publish.
In the top right-hand corner, you will see a grey Hidden button.
Step 2: Publish Your Gallery
Click on the grey Hidden button. From the Gallery Visibility drop-down menu, choose Published.
A grey Published button should appear, making your gallery viewable.
