Answer 2

If someone looking for a solution for this, The trick that I have found it.

so basically the solution is to pass the image url in the submitted-url field and don't pass the submitted-image-url parameter.

so instead of passing this:

{   
    "comment": "Check out developer.linkedin.com!",
    "content": {
        "title": "LinkedIn Developers Resources",
        "description": "Leverage LinkedIn's APIs to maximize engagement",
        "submitted-url": "https://developer.linkedin.com",  
        "submitted-image-url": "https://example.com/logo.png"
    },
    "visibility": {
        "code": "anyone"
    }
}

which will give:

you pass the following:

{   
    "comment": "Check out developer.linkedin.com!",
    "content": {
        "title": "LinkedIn Developers Resources",
        "submitted-url": "https://www.example.com/someimage.jpg"
    },
    "visibility": {
        "code": "anyone"
    }
}

which will give this:

Note that I don't pass submitted-image-url and description in the json. Description does not show on the post, so there's no point of passing anything in that field.
