As much as we would love to add the ability to share to Instagram, we’re blocked by Instagram’s policy that all uploads to Instagram must come from their own app. If Instagram decides to open up their platform, we’d love to add this ability!

You already have SHARE button content block, which includes FB, G+ and Twitter, but even more important are INSTAGRAM and PINTEREST as they are the most photo focused social media sites. Thank you.
