You can specify border graphics for the main screen of Photo Retailer to show your branding or a theme, etc.
The top, bottom, left and right graphics will display around the screen. Please create border graphics to scale for the monitor resolution you are using to ensure they display correctly without stretching, etc.
The graphics are combined as shown in the diagram below.
One easy way to create the graphics is to design the image with the same size as the monitor resolution then use the slice tool in Adobe Photoshop to carve it up.
The center piece is discarded as that's where Photo Retailer is displayed.
