Instagram is a social network based around sharing square pictures from your smartphone. Since the only way to upload pictures is from a mobile device (not a PC/Mac), the resolution of the images has been 640 x 640 ever since Instagram's launch in 2010. Since then though, cameras built into smartphones have come a long way and are capable of taking full HD pictures. This week, the source code on Instagram's website has revealed that photos are now being uploaded at 1080 x 1080 which suggests an update to the app in the near future will allow everyone to view the pictures at that quality.
