How did Instagram integrate with other social media platforms early on?

Instagram integrated with other social media platforms early on to expand its reach and make it easier for users to share their photos beyond the Instagram community. When Instagram first launched in October 2010, it allowed users to share their photos on three major social media platforms:

1. Facebook: Users could link their Instagram and Facebook accounts, enabling them to share their Instagram photos directly on their Facebook Timeline.
2. Twitter: Users could share their Instagram photos on Twitter with a link to view the image on Instagram's website. However, Instagram initially did not support Twitter Cards, which led to the display of cropped images in Twitter feeds.
3. Tumblr: Users could share their Instagram photos on Tumblr with a caption and links back to their Instagram profiles.

By integrating with these popular platforms, Instagram made it easy for users to share their photos with a broader audience, which helped drive user growth and engagement. Over time, Instagram has added support for additional social media platforms and expanded its integration options, allowing users to share their content across various channels and services.
