When you browse the web, your web browser stores (caches) a copy of the pages you visit (including images) on your computer. Storing a copy on your computer helps the browser load pages faster when you visit the same site again (or use the Back or Forward buttons). Periodically, you should clear this storage (cache) to help your browser function more efficiently.
