How to store Image from a web URL as an image file in Image field?

How to store Image from a web URL as an image file in Image field?

Hi all,

I'm new to Zoho Creator! 

I'm trying to save an image from a URL and generate public URL from creator.
I've understood how to generate a URL of an Image stored in the Image field.

The question is:
I'm rendering an Image from "https://www.expamle.com/taskID?apikey=xyz" as <img src='https://www.expamle.com/taskID?apikey=xyz'/> and it is working fine and displaying the image.

I want to store it in the image field itself and not use the URL every time I'm trying to view the image.
Is it possible to do it in deluge? If so how?

Thanks in advance!
Regards
Suhas
