How to Post Photos on Instagram through Website Without App
Instagram users no longer need the app to upload photos. The company is now rolling out the ability to upload photos through its mobile website. You can’t upload videos, add filters, upload to Stories, or send a direct message. Photo editing in general is limited — you can only rotate them or toggle between the square or wide crop — but still, you could conceivably build a profile from the website.
Instagram says, “Instagram.com (accessed from mobile) is a web experience optimized for mobile phones. It’s designed to help people have a fuller experience on Instagram no matter what device or network they are on.”
I believe the mobile upload feature is vital for Instagram’s global growth, as many people in developing countries like African countries, may not be able or may not want to download the app due to cellular connectivity and data concerns. So this option removes most restrictions and opens up a new experience.
Photo uploads are only available when the Instagram mobile site is accessed from an iPhone, iPad, Android or other smartphone or tablet. The desktop site does not allow for photo uploads. But with a desktop/laptop you can upload photos on Instagram when you change the URL to the mobile version that is from www.instagram.com to m.instagram.com. If you are using Chrome browser, to pick mobile display Just type Ctrl-Shift-I to bring up the Chrome developer window (ignore all the code inside) and then Ctrl-Shift-M to switch to the mobile version of the site.
Please try it and lets know your experience.
