Notice 2 things:
- Original image aspect ratio of the square photo is preserved (nothing is cropped out)
- Link "Instagram" points to the instagram page of the photo https://instagram.com/p/72U--QKh5EDiTeBDvqSpKqltAkgog3HwaWqGI0/
"We've also redesigned link page posts so that the aspect ratio for images is the same across desktop and mobile News Feed. Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping."
I have searched many blogs and [b]ios developer forum to get best answer of my problem but I am not unable to find it, make sure that shared image is 1.91:1 to prevent anything cropped out. Can anyone provide me a clear guideline/doc on how to share a "square" photo and preserving the aspect ratio displayed in facebook timeline (and provide a specific link to the photo page)?
