Here's what you do when you want to just snag a picture fast

drag & drop it to the desktop . Just left-click the picture, keep your mouse button down, then plop it onto your desktop. So easy. Of course, if your browser is maximized and you can't see your desktop this isn't going to work.

Select All

To select it all, use Ctrl + A. This keyboard shortcut will do the exact same thing. Just click once on the page you want to copy, press Ctrl and A at the same time and poof, it's done!
