I'm developing a method wich takes a logged FB user to my app and takes its profile picture. Is there a way to identify a picture as unique.

I mean, if 2 persons upload same picture, same picture name, can both have same picture id? is this picture unique? is there a way to get this picture as unique?

  • There is no such uniqueness. You would have to compare the actual image content to check whether two profile pictures are “identical”. – CBroe Mar 06 '18 at 15:08
  • The main problem is that my original "myimage.jpg" it's renamed to "randomnameprofile1.jpg" and "anotherrandomnameprofile2.jpg" when uploading to Facebook profile. Don't know how to compare original and uploaded one – Makros Mar 06 '18 at 15:35
  • he did not mean to compare image names, he meant to compare the actual content of the image... – andyrandy Mar 06 '18 at 15:42
  • btw. why tag this with js sdk AND php sdk? there is not even any code from any sdk... – andyrandy Mar 06 '18 at 15:42

  • _"Don't know how to compare original and uploaded one"_ - _what for_ would you need to "compare" them? What you actually want to achieve here eventually, is still pretty unclear. – CBroe Mar 06 '18 at 16:52
