Front Page 1:
The Front Page 1 widget area in the Gallery Pro theme demo uses one Text widget to display text and a button.
Gallery Pro comes pre-loaded with a default image that is used as the background for the Front Page 1 widget area. You may use this default image or go to Appearance > Customize > Front Page Background Images to upload your own. The default image size is 1600 x 900 pixels. Then go to Appearance > Widgets and add a text widget to the Front Page 1 widget area as shown.
