How to view instagram profile picture in full-size? [closed]

Question

I was able to view and download a person's full sized, high resolution profile picture on Instagram until even a few days ago. I usually remove the 's150x150' from the URL and it worked fine for me. But now when I try the same thing I get a error saying 'Invalid URL signature'. I don't know what's happened. Can someone find me a solution for this problem? Or an alternate method maybe?

Answer 1

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

Answer 2

You can even set the prof. pic size to its high resolution that is '1080x1080'

replace "150x150" with 1080x1080 and remove /vp/ from the link.
