When trying to mirror a tumblr blog, most of the pictures are not downloaded.
The UTLs to the pictures are in a script, and weirdly presented.

Thus:
      window['___INITIAL_STATE___'] = {
      ... lots of stuff elided ..
            	
"url":"https:\u002F\u002F66.media.tumblr.com\u002F0a0d8a0f0e3e4524d5b48f1b9138d31a\u002Fe4ec3e0ca9656520-90\u002Fs540x810\u002F950529433fcf7d7b2587ffb41761e2636c30e465.jpg"}]},

The forward slashes in the URL are encoded as \u002F, and the images are not
captured.

Is there any way to get this to work?
