OK now you have images in your gallery. Next step is to select gallery template. In Edit Gallery Page, you will find “Galleries Options” box. Then select “Gallery Template” you want. In this case, selected “Gallery Fullscreen”.
Next “Make Menu Transparent” option. Check this option to display main menu in transparent (support if upload gallery header image using set featured image option)
Lastly, you can upload gallery’s cover image using “set featured image” box and it will display as gallery page header.
Sorting Images in The Gallery
