The context menus module allows you to add items to Google Chrome's context menu.

You can choose what types of objects your context menu additions apply to, such as images, hyperlinks, and pages.

You can create as many context menu items as you need, but if more than one from your extension is visible at once, Google Chrome automatically collapses them into a single parent menu.

Manifest

You must declare the "contextMenus" permission in your extension's manifest to use the API. Also, you should specify a 16x16-pixel icon for display next to your menu item. For example:

{
  "name": "My extension",
  ...
  "permissions": [
    "contextMenus"
  ],
  "icons": {
    "16": "icon-bitty.png",
    "48": "icon-small.png",
    "128": "icon-large.png"
  },
  ...
}

Examples

You can find samples of this API on the sample page.
