How to send image path in Web API

[raxitpandya]

tokenData = {
            "profileName" : p.profileName,
            "contentRating" : p.contentRating,
            "isKid" : p.isKid,
            "dob": "2010-05-15",
            "languageIds": LangIds,
            "profileImage": "/assets/images/profile/img-6.png"
        }
 than converting to Json format as per below line
body = FormatJSON(tokenData)
But due to "/assets/images/profile/img-6.png"  path i am getting 500 error.
I check with this path : "../../abc.png" and it is working. Please let me know how to send this "/assets/images/profile/img-6.png" to server
Thank you.
