Just wanted to make a quick post about AW particularly, but it probably works elsewhere. There's a slightly easier way to get these saved in Google Chrome that doesn't require extensions and what-not.
-Open the full size photo you want, and right click somewhere in the white border.
-Select "inspect element."
-This opens a small window in the foreground, so click the magnifying glass at the bottom and then hover over the image in the original window, it should go blue. Click it.
-This brings up the URL of the image in the "inspect element" window which you can click, and that brings up the image.
-Right click it, open the image in a new tab, then just save it.
This might sound a little long-winded as an explanation, but it's super quick and easy once you get in a rhythm. If you keep the "inspect element" window open, you don't have to click the magnifying glass each time, too.
