Hi there!
Thanks for contacting AddThis Support 🙂
Unfortunately, we do not support Instagram share and the reason is because of their terms of service on their API. Instagram users are only allowed to post images owned by the account owner which means that random visitors on someone’s site are not allowed to share that site’s images without written permission from the image rights owner.
As soon as Instagram decides to change this policy and provides sharing endpoints, then we will add them to our services.
Thanks,
Leland
