Whether you're gasping at the beauty of Earth or the wonder of modern-day architecture (or both), there may well be times when you need to quickly download all of the pictures on a particular page -- even if you just want some new phone backgrounds to use. One such tool for the job is the I'm A Gentleman extension for Chrome.
Install the add-on and you find yourself with a new toolbar button: click on it, grant it permission, and all of the images on the current page are swiftly transferred to the default download folder. Make sure automatic downloads are set from the Chrome settings tab, otherwise you'll be greeted with a flurry of download dialogs on screen.
I'm A Gentleman has a couple of other tricks up its sleeve too: it lets you save single images via Alt+click or by dragging them slightly to the left or right on the page with the mouse (behaviour you can switch off in the extension options if you want to). If you're regularly downloading a bunch of pictures from pages, it could be a real time saver.
Hat tip to Ghacks for spotting the extension.
