Widget JS SDK to Upload a photo to a record in a Module

Widget JS SDK to Upload a photo to a record in a Module

Good day, 
I would really appreciate it if someone can assist me. I have written a widget, to be used in a Custom Module in CRM. 

My goal: I want to upload a photo from my computer and display it in die "upload image" field.


1. I upload the file to ZFS by using the SDK: See screenshot. SaveFileSDK.png.
2. I get a success response that the file has been uploaded, and the unique id is returned. See screenshot: FileUploadedSuccesfully.png
3. I update a record's Image_Upload_1 field by passing the long id received in the response after I had uploaded the photo to the ZFS.
4. A success message is received back, saying the record had been updated. See screenshot: SuccessRecordUpdated.png
 
So far so good, however, when I open the record, the image file is NOT VISIBLE in the said field. Why is that? Can anyone help me please?
