The LR/Instagram plugin does exactly what you think it does: it lets you post images to Instagram directly from Lightroom. No need to export and use some third party Web client or get the photo onto your smartphone.
Once you install the plugin and authorized your Instagram account (or several accounts), you’re good to go. Simply drag the photo into the publish collection that matches the IG account you want to post to, fill in caption and tags, have the plugin crop or pad your photo to fit Instagram’s parameters, and hit Publish.
The LR/Instagram plugin is 100% free to download and try, the makers simply ask that you show your support by registering it for $10 from Lightroom Plugin Manager if you like it. It’s compatible with Lightroom CC/3.0 and higher, and works for both Windows (XP or later) and Mac OS X (10.7 or later).
