Constrain a single image in your browser to be full width. Useful for implementing design mocks.
Important: This will only affect actual images opened in Chrome, not images in a web page.
Step 1: Open the extensions page and check "Allow access to file URLs".
Step 2: Open an image from your computer in Chrome.
Step 3: Click the Full Width Image extension.
Done, your image is now the full width of the browser window.
