It is not recommended that a large image be created to fill the entire application background. These can cause event issues and frustrate users. Instead, an image can be created that is fixed to an edge of the browser window and fades to a background colour, which can be defined to match the image. In this way, the page length increases, and the background will not accidentally repeat, maintaining the branding.
Images can be fixed to the top or bottom of the page, so the example above could be modified so that the tickets are coming from the bottom of the screen.
