How to upload an item image via REST webservice

Content

I am trying to upload an item image using Rest web service. It does not seems to loading my image even though I am getting 201 created. It shows my file name not the image. Can someone please advice if I made any mistake in my payload

My Payload as below:

{

    "OrganizationCode": "000",

    "ItemClass": "Automotive",

    "ItemNumber" : "AA_6", 

    "ItemDescription" : "add image",

    "ItemAttachment": [

    {

        "DatatypeCode": "FILE",

        "Description": "Example Home page",

        "FileName": "thESRVUZ3V.jpg",

        "FileUrl": "/Users/devic/Desktop",

        "Title": "My first file upload",

        "CategoryName": "IMAGE"

    }

    ]

}

 

Thank you
