Instagram Now Supports Photo Uploads From Mobile Site
Prior to the update, Instagram only allowed photo uploads from its mobile apps, and the iOS app is limited to the iPhone, so iPad users were forced to download an iPhone-only app with an unoptimized layout to upload photos to the social network.
The Instagram website on mobile devices was previously only available for browsing photos, liking content, searching, and viewing notifications, but now it's possible to upload photos.
But it sounds like there still isn’t a first-class iPad experience, and you can’t upload from a Mac unless you set your browser to use the mobile version of the site.
