Q1 : If I remembered correctly you can just open a new tab and then drag and drop the picture into the new tab page.

Q2 : Pretty sure you can find this option in the browser's settings.

Q3 : Try this extension called "Grab Any Media". https://chrome.google.com/webstore/detail/a...gkgfapdog?hl=en

There are tutorials so you can learn how to use it.

But seriously though, you can find all these with a simple Google search.

Cheers!
