add images to rich text area fields in knowledge articles via rest api

Hi, I am a newbie to salesforce knowledge and I have been trying to publish articles to salesforce lightning knowledge via REST API. I am having trouble figuring out the way to add an image in rich text field areas in articles via APIs for a while now. From the UI,  when I click the image option in the UI, it creates a link like this

<img alt="" src="https://c.ap17.content.force.com/servlet/rtaImage?eid=ka02x0000005Qny&feoid=00N2x000000xPaN&refid=0EM2x000000PW60" />

I could not figure out how to upload articles to this servlet and get back a similar URL as a response, so that I can use these links in rich text areas. Can someone point me in the right direction?

Thanks,
Rajasekhar

Hi Rajasekhar,

That domain (c.ap17.content.force.com) is checking the session and hence the image is private.  Make the site public.

Review below link for same.
