Background
I'm developing an standard FAQ using Knowledge Base Articles. I've defined an Article Type FAQ which contains a Rich Text field called "Answer".
The FAQ articles are exposed to an external web site through a custom Apex web service. That WS query and sort the content that should be render by the external site.
This Apex hit the FAQ_kav object to get the field content.
Note: the WS is hit by a full access API user.
So far, everything is working fine, but:
Issue
When the user insert an inline image using the Rich Editor's upload function, that image is store in something like: https://c.cs20.content.force.com/servlet/rtaImage?eid=ka3m0000000XXXX&feoid=00Nm0000000XXXX&refid=0EMm0000000XXXX
That domain (c.cs20.content.force.com) is checking the session and hence the image is private. Even when I've checked the article for Public Knowledge Base channel.
I understand that that image will be stored as a document, but I'm not abled to check as "Externally Available Image" for standard docs.
Question
Is any security setting that I should enabled in order to expose public access to that content(images).
Best Answer
You can expose the image through a site. You only need to change the instance url by the site home page.
Also, you need to establish the article as public.
Site Profile Changes:
Set field where image is placed as visible.
Set Read permission to object where image is placed.
Go to "Category Group Visibility Settings" section and set visibility to "All Categories" in the article/s group/s.
For example:
If you have this site:
And your original image url is:
Your public image would be:
This workarround would work with any image in a Rich Text Area.
