What are breadcumbs?
From Wikipedia: Breadcrumbs or breadcrumb trail are a navigation technique used in user interfaces. Its purpose is to give users a way to keep track of their location within programs or documents.
Only 1 image is used for creating this navigation which is the seperator. It is a bigger image than the displayed one considering the breadcrumb will be scaled when needed.
