You want to upload a photo in your Instagram account from your PC or Mac but you cannot. Instagram doesn’t allow a user to post the photos from your PC or Mac. The company wants you to share photos from your daily lives instantly without heavy editing through your desktop. But there is always the other way around.
If you’re on a PC and using Google Chrome, it’s a bit easier to get the camera button to appear. Log into your Instagram and right click the page (anywhere) to get a drop down menu. Select Inspect and click on the Tablet icon. This will automatically switch your page to mobile view, which grants access to the camera upload button.
That’s it, Enjoy!!!
