What does the state: Available conditionally mean on the sys_attachment table?

And would this prevent an image from displaying in a Knowledge article?
I'm seeing some broken images and checking this table it appears most of them are set to this state. Does anyone know what this state means?

Hi @cherylkirkn ,

Users cannot make updates to the attachment manually. 

The state of the attachment depends on the Anti-Virus scan results. 

Below are the states of an attachment: 

• <Empty>: for all existing attachments we will have empty state, that means attachment did not go through antivirus scanning
• Available: the attachment went through antivirus scan and is a clean file
• Not Available: the attachment went through the scan and found to be a malicious file
• Pending: the attachment was just uploaded and waiting in the antivirus scan queue
• Available Conditionally: the attachment was downloaded without going through scanning (force download option was selected and scan server has some issue to scan this attachment)
  • Available conditionally is specific to download case. It will be set to a different state (available or not available) in next attempt of download and scan server should be available.

I've already read the documentation. This is just that. I am curious what is the value, how is it triggered, what's it used for?
