To change your profile on your LinkedIn account, you’ll first need to log in to LinkedIn then hover over the profile option here and click “Edit Profile.” Here, you’ll see your current profile image and the Change Photo option. Here, you’re going to look for the Change Photo in blue text, go ahead and grab the new photo that you want to upload. Now, LinkedIn recommends that this image be 400×400 pixels wide with a minimum pixels size of 300×300.

Also, remember that LinkedIn is a professional network, therefore you want to have a professional headshot and maybe not the same image that you’re using in Facebook.
