Finally! You can upload to Instagram from a browser. To do so, in your browser, turn on developer mode, then spoof a mobile browser, and you’ll get the camera icon to upload from your desktop. For the less tech savvy, spoofing a mobile browser means you’re telling Instagram, you’re on a mobile device instead of a desktop. This “hack” is also useful because you can upload up to 10 photos at a time to Instagram now too.
