I want to get the the original picture out of this Facebook link:
https://fbexternal-a.akamaihd.net/safe_image.php?d=AQCPdu0qFIMkMPGN&w=470&h=246&url=https%3A%2F%2Fscontent-lax3-1.xx.fbcdn.net%2Fhphotos-xfp1%2Fv%2Ft1.0-9%2F12705743_10153625263299678_1238692121976712825_n.jpg%3Foh%3D0f330b83cd6f52cba12b06ea141af571%26oe%3D5723078F&cfs=1&upscale=1&sx=1&sy=0&sw=558&sh=292&ext=png2jpg
What I usually do is get the value of url parameter and decode it to get the S3 link.
The result of applying this to this link is
https://scontent-lax3-1.xx.fbcdn.net/hphotos-xfp1/v/t1.0-9/12705743_10153625263299678_1238692121976712825_n.jpg
But it gives me 403 response. How should I obtain the link of the original photo?

And obtained:
Which works fine.
Apparently the oh and oe parameter are essential. Here the minimal working link:
