How To Upload Photo On Instagram Using Computer
How to post images to Instagram from a desktop computer internet browser
The majority of web browsers have a way of allowing you alter the "Individual Agent"-- the thing that informs an internet site what kind of gadget you get on. So, also when you're on a laptop or desktop, you can trick a website like Instagram into revealing you the mobile website. That's what we're going to do.
Safari
On Safari, it's simple. Most likely to Safari > Preferences > Advanced. Check the box at the very bottom that claims, "Show Develop menu in menu bar"
Now open up a private surfing window. Visit Develop > User Agent > Safari - iOS 10 - iPhone. Most likely to Instagram.com, sign in and click the camera switch at the end of the screen to upload a picture from your desktop computer.
Chrome
In Chrome, most likely to Instagram.com as well as sign in. Now right-click the page > Inspect > click the Tablet icon (top-left). The page must change to mobile view, where you'll find a camera button at the bottom of the screen, which lets you post a photo from your desktop.
Several Instagrammers-- myself included-- fire pictures on a dSLR electronic camera as well as modify them on their computer system prior to uploading to Instagram. That means having to move the completed image to a phone (through AirDrop or email), which is cumbersome, at best.
This workaround cuts that step out, making dSLR uploads much easier than ever.
