How To Upload Pictures On Instagram From Computer
How to upload images to Instagram from a desktop web browser
Many web browsers have a means of letting you change the "Individual Representative"-- the important things that informs a site what sort of tool you get on. So, also when you're on a laptop or desktop, you can deceive a site like Instagram into showing you the mobile site. That's just what we're going to do.
Safari
On Safari, it's easy. Go to Safari > Preferences > Advanced. Check the box at the very bottom that says, "Show Develop menu in menu bar"
Now open an exclusive browsing home window. Head to Develop > User Agent > Safari - iOS 10 - iPhone. Go to Instagram.com, log in and click the camera button at the end of the screen to post a photo from your desktop computer.
Chrome
In Chrome, go to Instagram.com and log in. Now right-click the page > Inspect > click the Tablet symbol (top-left). The page should switch over to mobile view, where you'll locate a camera button at the bottom of the display, which lets you publish a picture from your desktop computer.
Many Instagrammers-- myself consisted of-- shoot pictures on a dSLR camera and also modify them on their computer prior to posting to Instagram. That means having to move the completed picture to a phone (using AirDrop or email), which is troublesome, at best.
This workaround reduces that step out, making dSLR uploads simpler than ever before.
